1 Introducing Release 12.1
1-8
•The ability to have error statistics determine the duration of the simulation
•A more flexible integrator block
The Communications Blockset 2.0.1 online documentation set now includes a
new document, called “Getting Started with the Communications Blockset.”
Control System Toolbox 5.1
Major enhancements to the Control System Toolbox 5.1 include:
•Several important enhancements to the SISO Design Tool to make it more
powerful and easier to use
•Enhancements to controls algorithms, such as:
- M-circle support in the
nyquist function
- A new function,
bandwidth, that calculates the bandwidth of SISO systems
- For LTI models with complex data, an option to specify transfer functions
or state-space models with complex coefficients
Data Acquisition Toolbox 2.1
Major enhancements to the Data Acquisition Toolbox 2.1 include support for:
•The following additional National Instruments boards:
- 445x Dynamic Signal Acquisition (DSA) Series boards
- Analog output boards
- Digital I/O boards (no streaming)
•High resolution (greater than 16-bit) sound cards. Note that some sound card
drivers may not support this feature because they are still in beta.
Database Toolbox 2.2
Major enhancements to the Database Toolbox 2.2 include:
•Retrieval of data as numeric, structure, or cell array format, as specified via
preferences. In previous versions of the Database Toolbox, only the cell array
format was supported. The numeric format allows for a significant reduction
in memory usage. The structure format allows the retrieved data to be
accessed as a MATLAB structure.
