Major Bug Fixes This bug fix introduces a backwards incompatibility. When A is a function Afun and sigma = 'sm', Afun must now return Y = A\x. Prior to MATLAB 6.1, eigs required Afun to return y = A*x for this case. quad Sampling Improved In MATLAB 6.0, quad('cos(4*n*x)',-pi,pi) returned 2*pi instead of 0. When quad initially sampled the function, it incorrectly assumed the function is the constant 1 over the interval [-pi,pi] and so returned 2*pi early. It now samples more carefully and returns 0.

2 MATLAB 6.1 Release Notes You May Need to Overwrite the MATLAB Default Choice of BLAS On the PC, under both Linux and Windows operating systems, MATLAB determines at startup time what processor your computer has, for example Genuine Intel Pentium II, Pentium III, or AMD Athlon. MATLAB then automatically selects the most appropriate BLAS for your processor. The same is true on the SUN, where MATLAB distinguishes between UltraSPARCs and non-Ultra machines.
PAGE 71
Platform Limitations Determining Your Processor This section indicates how you can determine what type of processor your computer has. ALPHA. Enter the command /usr/sbin/psrinfo -v which returns something like Status of processor 0 as of:05/03/01 17:16:55 Processor has been on-line since 04/20/2001 14:09:31 The alpha EV4.5 (21064) processor operates at 233 MHz, and has an alpha internal floating point processor.

HPUX. MATLAB only supports HPUX running on PA-RISC2.0. IBM_RS. Contact IBM Technical Support and request the document entitled “Determining CPU Speed in AIX.
PAGE 73
Platform Limitations Using Another BLAS You may also use BLAS from other sources than the ones shipped with MATLAB, provided they are in the correct format. This format is a shared library (as opposed to a static library) that exports all the double-precision (starting with d) and double-precision complex (starting with z) BLAS routines from dasum to zupmtr.

Upgrading from an Earlier Release no longer produces any output. Prior to Release 12, a background command sent output to the command window. If you need to see the output from a command, either do not make the command a background command (i.e., remove the &), or run the background command in a separate xterm. To start another xterm, issue the following command. ! xterm & In Release 12, foreground functions (i.e.

2 MATLAB 6.1 Release Notes External Interfaces/API Issues Concatenation of Java Objects When you concatenate Java objects, the class of the resultant object depends on the classes of the input objects, as follows: • If the input objects are of the same class, MATLAB makes the output object of that class. This was true in Version 6.0 as well. • If the input objects are of different classes, but all inherit from a common class, MATLAB makes the output object of the common parent class.

3 Simulink 4.1 Release Notes New Features This section introduces the new features and enhancements added in Simulink 4.1 since Simulink 4.0 (Release 12.0). For information about Simulink features that are incorporated from recent releases, see the Release Notes for Release 12. Note For information about closely related products that extend Simulink, see the sections on the Simulink Performance Tools and the Real-Time Workshop, as well as information about the blocksets from The MathWorks.
PAGE 85
New Features Autoconnecting Blocks This version makes connecting blocks significantly easier. To connect a set of source blocks to a target block, simply select the source blocks, hold down the Ctrl key and left--click the target block. Simulink draws connecting lines between the source blocks and the destination block, neatly routing lines around intervening blocks. To connect a source block to a set of target blocks, select the target blocks, hold down the Ctrl key and left--click the source block.
PAGE 86
3 Simulink 4.1 Release Notes Modeling Enhancements This section describes enhancements to Simulink’s dynamic system modeling tools. Autorouting Option Added to add_line Command The add_line command now optionally routes lines around intervening blocks and annotations. For example, the following command autoroutes a connection between two blocks in the vdp model. add_line('vdp','Product/1','Mu/1','autorouting','on') The autorouting option is off by default.
PAGE 87
New Features Saving Block User Data in Model Files This version adds a new block parameter, named UserDataPersistent, that is off by default. Setting this parameter on, e.g., set_param(block-name,'UserDataPersistent','on') causes Simulink to include a block’s user data (i.e., the value of the block’s UserData parameter) in the model file when you save a model. Simulink encodes the user data as ASCII characters and saves the encoded data in a new section of the model file called MatData.
PAGE 88
3 Simulink 4.1 Release Notes Enhanced Engine Model Demos The top and bottom dead center detection in the engine and enginewc demo models now use a reset integrator. In previous versions, the models used a triggered subsystem to detect angular position. This method resulted in inefficiencies and a slower, less accurate solution. In addition, self-triggering subsystems are now illegal in Simulink. Setting Block Sorting Priority on Virtual Subsystems In Simulink 4.
PAGE 89
New Features Such models cannot be correctly simulated. Accordingly, Simulink now displays an error message when you attempt to run or update a diagram containing function-call cycles. Simulink Debugger This section describes enhancements to the Simulink debugger. Enhancement to Sorted List Display The Simulink debugger (sldebug) sorted list command, slist, now displays the names of the S-functions residing inside S-function blocks.
PAGE 90
3 Simulink 4.1 Release Notes Block Library This section describes enhancements to the Simulink block libraries. Unified Pulse Generator This version merges the Discrete Pulse Generator block into the Pulse Generator block. The combined block has two modes: time-based and sample-based (discrete). Time-based mode varies the step size when a variable step solver is being used to ensure that simulation steps occur at pulse on/off transitions.
PAGE 91
New Features Sine Wave Block Enhancements The Sine Wave block now supports a bias factor that eliminates the need to sum with a Constant block. The Sine Wave block also has a new computational mode. This mode (called sample-based) eliminates the dependence on absolute time. Enhanced Flip-Flop Blocks Simulink Extras (simulink_extras.mdl) contains a set flip-flop blocks. These blocks now use the new triggered subsystem latching semantics.
PAGE 92
3 Simulink 4.1 Release Notes Bug Fixes This section lists fixes to bugs that occurred in the previous version of Simulink. • Variable sample time S-functions Simulink no longer crashes when an S-function with variable sample time is placed in an atomic subsystem. • Bus selector detection of duplicated names A bug related to the detection of a duplicated name in a bus that was feeding a Bus Selector block was fixed. • Optimize block memory use In Simulink 4.
PAGE 93
Bug Fixes • Sorting bug fix Previous versions incorrectly computed the direct feedthrough setting for nonvirtual subsystems in triggered/function-call subsystems. This resulted in incorrect execution (sorting) orders. Now all nonvirtual subsystems within triggered subsystems have their direct feedthrough (needs input) flags set for all input ports.
PAGE 94
3 Simulink 4.1 Release Notes Platform Limitations for HP and IBM Note The Release 12 platform limitations for Simulink for the HP and IBM platforms still apply to Release 12.1. In addition, there are more limitations, described below. The following Java-dependent Simulink features, introduced in Simulink 4.1, are not available on these platforms.
PAGE 95
Upgrading from an Earlier Release Upgrading from an Earlier Release This section discusses upgrade issues in moving from Simulink 4.0 to Simulink 4.1. See the Release Notes for Release 12 for upgrade issues involved in moving from Simulink 3.0 (Release 11.0) to Simulink 4.1. Running Simulink 4.1 Models in Simulink 4.0 Simulink 4.0 can run models created or saved by Simulink 4.1 as long as the models do not use features introduced in the new version, including new block types and block parameters.
PAGE 96
3 Simulink 4.1 Release Notes S-Functions Sorted Like Built-In Blocks When sorting blocks, Simulink now treats S-function blocks the way it treats built-in blocks. This means that S-functions now work correctly in nonvirtual subsystems when there is a direct feedback connection (in Simulink 4.0 and prior, this wasn't the case). It also means that models compile (update diagram) faster.
PAGE 97
Upgrading from an Earlier Release additive signals). This resulted in an implicit delay. Now you must explicitly define the delay by inserting a memory block. Improved Invalid Model Configuration Diagnostics This version of Simulink does a better job of detecting and flagging invalid modeling constructs in Simulink models. Consequently models that ran in previous versions of Simulink (sometimes producing incorrect results) may not run in the current release.

5 Real-Time Workshop 4.1 Release Notes Build Directory Validation The build process now disallows building programs in the MATLAB directory tree. If you attempt to generate code in the MATLAB directory tree, an error message will be displayed prompting you to change to a working directory that is not in the MATLAB directory tree. On a PC, you can continue to build in the directory matlabroot/Work.
PAGE 109
New Features Code Readability Improvements Improvements to the readability of generated code include: • Elimination of redundant parentheses. • Long C statements in the generated code are now split across multiple lines. • Block comments are more informative. Control Flow Blocks Support Simulink 4.1 implements a number of blocks that support logic constructs such as if-else and switch, and looping constructs such as do-while, for, and while. The Real-Time Workshop 4.
PAGE 110
5 Real-Time Workshop 4.1 Release Notes External Mode Enhancements Inline Parameters Support The Real-Time Workshop now lets you use the Inline parameters code generation option when building an external mode target program. When you inline parameters, you can use the Model Parameter Configuration dialog to remove individual parameters from inlining and declare them to be tunable.
PAGE 111
New Features Include System Hierarchy in Identifiers When this option is on, the Real-Time Workshop inserts system identification tags in the generated code (in addition to tags included in comments). The tags help you to identify the nesting level, within your source model, of the block that generated a given line of code. See “Include System Hierarchy in Identifiers” in the Real-Time Workshop User’s Guide for further information.
PAGE 112
5 Real-Time Workshop 4.1 Release Notes For further information, see “Block States: Storing and Interfacing” in the Real-Time Workshop User’s Guide. Support for tilde (~) in Filenames on UNIX Platforms All filename fields in Simulink now support the mapping of the tilde (~) character in filenames. For example, in a To File block you can specify ~/outdir/file.mat. On most systems, this will expand to / home/$USER/outdir/file.mat. The Real-Time Workshop uses the expanded names.
PAGE 113
New Features Cleanup of Block I/O Connection Handling in TLC The handling of signal connections in rtw/c/tlc/blkiolib.tlc and rtw/ada/ tlc/blkiolib.tlc was reworked. See the discussion of LibBlockInputSignal in “TLC Function Library Reference” in the Target Language Compiler Reference Guide. Literal String Support If a string constant is prefixed by the L format specifier, then no escape character processing is performed on that string.
PAGE 114
5 Real-Time Workshop 4.1 Release Notes • Zero indexing on complex numbers is now supported. In prior releases, the Target Language Compiler allowed 0 indexing for integer and real values, but not for complex values. This restriction has been removed in the Target Language Compiler 4.1, as shown in the following example. %assign a = 1.0 + 3.0i %assign b = a[0] %% zero index now allowed • Fixed a crash that occurred if ROLL_ITERATIONS was called outside of a %roll construct.
PAGE 115
Bug Fixes Bug Fixes The Real-Time Workshop 4.1 includes the bug fixes described in this section. See also “TLC Bug Fixes” on page 5-9 for bug fixes specific to the Target Language Compiler. Block Reduction Crash Fixed A problem that crashed MATLAB due to a segmentation fault during the block reduction process has been fixed. This problem occurred only if the Block Reduction option was on, and if a Scope block was connected to a block that was removed due to block reduction.
PAGE 116
5 Real-Time Workshop 4.1 Release Notes Correct Code Generation of Fixed-Point Blockset Blocks in DSP Blockset Models A code generation bug involving some DSP Blockset blocks (see list below) was fixed. When these blocks were driven by a block from the Fixed-Point Blockset, generated code would write outside array memory bounds.
PAGE 117
Bug Fixes Fixed Error in commonmaplib.tlc A typo in rev 1.17 of commonmap.tlc was fixed. This typo caused an error during code generation, when using the grt_malloc target with External mode selected. Fixed Name Clashes with Run-Time Library Functions The Real-Time Workshop now uses the macros rt_min and rt_max to avoid clashing with run-time library min and max functions.
PAGE 118
5 Real-Time Workshop 4.1 Release Notes Removed Unnecessary Warnings and Declarations from Generated Code Several unnecessary warnings and declarations in the generated code have been removed. These include: • In functions where the tid argument is not referenced, the declaration (void)tid is no longer generated. (The tid argument is required because the function API is predefined.) • Warnings involving const casts were suppressed in some of the rtw/c/libsrc modules. Retain .

Upgrading from an Earlier Release For further information see “Simulink Data Objects and Code Generation” in the Real-Time Workshop User’s Guide. S-Function Target MEX-Files Must Be Rebuilt S-function MEX-files generated by the S-function target under Release 11 are not compatible with Release 12. The incompatibilities are due to new features, such as parameter pooling, introduced in Release 12.0. If you have built S-function MEX-files with the S-function target under Release 11, you must rebuild them.
PAGE 122
5 Real-Time Workshop 4.1 Release Notes Obsolete Code Generation Variables The code generation variables FunctionInlineType and PragmaInlineString are now obsolete. These variables controlled the generation of inlined functions. In the current release, you can generate inlined functions from subsystems, as described in “Nonvirtual Subsystem Code Generation” in the Real-Time Workshop User’s Guide.
PAGE 123
Known Software Problem Known Software Problem This section updates the Real-Time Workshop 4.1 documentation set, reflecting a known software problem. Turn the New Wrap Lines Option Off The MATLAB Command Window has a new Wrap lines option. Real-Time Workshop frequently displays very long message lines as a build progresses. This can cause some display problems. Therefore, when using Real-Time Workshop, you should turn the Wrap lines option off using the Preferences setting.

12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes Introduction to Developer’s Kit for Texas Instruments™ DSP The Developer’s Kit for Texas Instruments™ DSP 1.1 is a new product that is included on our product CD for the first time in Release 12.1 Note The Developer’s Kit for Texas Instruments™ DSP 1.0 was released as a Web-downloadable product prior to Release 12.1. Version 1.1 of this product includes some important updates to Version 1.0, as summarized in “New Features” on page 12-4.
PAGE 157
Introduction to Developer’s Kit for Texas Instruments™ DSP The Developer’s Kit lets you use Simulink to model floating-point digital signal processing algorithms from blocks in the DSP Blockset, and then use the Real-Time Workshop to build ANSI C code targeted to the TMS320C6701 EVM (C6701 EVM). The Developer’s Kit takes the generated C code and uses Texas Instruments (TI) tools to build C6701 EVM-specific machine code.

12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes New Features Note The Developer’s Kit for Texas Instruments™ DSP 1.0 was released as a Web-downloadable product prior to Release 12.1. Version 1.1 of this product includes some important updates to Version 1.0, as summarized below. New Link Functions for CCS IDE Version 1.1 of the Developer’s Kit adds five functions that extend the program debugging and project management capabilities of the tool.
PAGE 159
New Features New Interface Between the Developer’s Kit and FDATool If you own the Filter Design Toolbox or the Signal Processing Toolbox, you can design filters in Filter Design and Analysis Tool (FDATool) and export those filter designs directly to CCS IDE and to your target. You do not need to export the filters to your MATLAB workspace first. With this link, you can design filters, export them to your target, and test them in your signal processing application.
PAGE 160
12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes New Run-Time Libraries To reduce the size of the generated .out files when you build models for targeting, and to improve the efficiency of the resulting file, the Developer’s Kit now uses run-time libraries to include many block functions in the .out file. When your model uses one of a number of DSP blocks, the .out file generated by the compile uses the .obj file for the block from the run-time library that is appropriate for the target.

12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes Major Bug Fixes The following problems identified in Version 1.0 have been fixed in this release: • Your C6701 EVM no longer has to be the first board in your computer. In Version 1.0, your evaluation module had to be board 0, with its processor as processor 0. In this release, you can install your C6701 EVM in any position, and identify it specifically when you use it as your target.
PAGE 163
Upgrading from an Earlier Release Upgrading from an Earlier Release Version 1.1 of the Toolbox incorporates significant changes to the targeting options, the CCSDSP object, and the way Simulink blocks are generated. New Libraries at Run-Time The Developer’s Kit now uses run-time libraries to include many block functions in the .out file. Refer to “New Run-Time Libraries” on page 12-6 for more information about how this change affects your existing models.

12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes Known Software and Documentation Problems This section updates the Developer’s Kit for Texas Instruments DSP 1.1 documentation, presenting the known problems with the software and documentation. Each entry in the following sections describes a situation you may encounter when you use the Developer’s Kit.
PAGE 165
Known Software and Documentation Problems cc = ccsdsp: . . % Interact with CCS IDE. . . vstate = cc.isvisible; % Store visibility state for CCS. cc.visible(0); % Force CCS to the background. x = cc.read('FF00','int32',[20 20],20); % Large read transfer. cc.write('FF00',int32(randn(20)),20); % Large write transfer. cc.visible(vstate); % Return CCS to its previous visibility state. . . % Continue to interact with CCS IDE. . . • CCS limits memory read and write data transfers to 32 KB.
PAGE 166
12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes • When you configure your target code to perform RTDX write operations (write data from the target to the host) on the C5402 DSK, you must poll the ‘successful emptying of the write buffer’ status. The C6000, which allows polling or host-initiated interrupts, does not require polling. The following code provides an example of the polling syntax, where ochan is the write channel.
PAGE 167
Known Software and Documentation Problems 2 Open modelname.bld for editing in MATLAB. 3 Within modelname.bld, find the section /*add include paths*/. 4 Highlight and copy the paths listed in the section. You are going to use these paths to update the path definition for your project in CCS IDE. 5 Switch to CCS IDE. 6 Select Project->Options from the menubar. Click Compiler on the Build Options dialog to see the dialog shown here.
PAGE 168
12 Developer’s Kit for Texas Instruments™ DSP 1.1 Release Notes 7 In the Include path area marked in the figure, append the text you copied from modelname.bld to the end of the existing path. Do not overwrite the existing path entries. 8 Click OK to close the Build Options dialog. 9 Select Project->Scan All Dependencies... from the CCS IDE menubar. CCS IDE scans the new include paths and updates the file information. Now you can view all of the header files in the Include directory in CCS IDE.
PAGE 169
Known Software and Documentation Problems • When you read an 8-bit integer from the processor into MATLAB, the read function takes 16 bits from processor memory, discards the eight most significant bits, and returns the remaining eight bits to MATLAB as the integer value. For these reasons, scripts that run on C6000 family processors may not run without modification on C5000 family processors.
