Detecting Excessive Sample Rates
If your specified sample rate is too fast, the Real-Time Windows Target detects
and reports this during real-time execution. Sampling rates exceeding 10 kHz
can be achieved on Pentium computers. Once the model is running, the
rtwho
command can be issued in the MATLAB command line to observe the system
performance. As indicated, MATLAB performance decreases as the system
becomes overloaded:
Real-Time Windows Target version 2.5.0 (C) The MathWorks, Inc.

Demo Library
The demo library includes models with preset values and dialog boxes. These
models include a configuration of examples that use no I/O, A/D only, A/D and
D/A in a simple signal processing demo, as well as in a simple control demo.
Examples that use I/O blocks require you to configure the Adapter block to
match the I/O board installed in your computer.
1 In the MATLAB window, type
rtwtdemo
The rtwtdemo window opens and displays the demo models provided with
the Real-Time Windows Target.
