2 Simulink and the DSP Blockset
2-12
Using dspstartup.m
There are two ways to use the dspstartup M-file to preconfigure Simulink for
DSP simulations:
•Run it from the MATLAB command line, by typing
dspstartup, to
preconfigure all of the models that you subsequently create. Existing models
are not affected.
•Place a call to
dspstartup within the startup.m file. This is an efficient way
to use
dspstartup if you would like these settings to be in effect every time
you start Simulink.
If you do not have a
startup.m file on your path, you can create one from the
startupsav.m template in the toolbox/local directory.
To edit
startupsav.m, simply replace the load matlab.mat command with a
call to
dspstartup, and save the file as startup.m. The result should look like
something like this.
%STARTUP Startup file
% This file is executed when MATLAB starts up,
% if it exists anywhere on the path.
dspstartup;
The default settings in dspstartup will now be in effect every time you launch
Simulink.
For more information about performing automated tasks at startup, see the
documentation for the
startup command in the “MATLAB Function
Reference.”
Customizing dspstartup.m
You can edit the dspstartup M-file to change any of the settings above or to
add your own custom settings. For example, you can change the
'StopTime'
option to a value that is better suited to your particular simulations, or set the
'SaveTime' option to 'on' if you prefer to record the simulation sample times.
