Communications Blockset™

commstartup - Default Simulink^® model settings for Communications Blockset™ software

Syntax

commstartup

Description

commstartup changes the default Simulink model settings to values more appropriate for the simulation of communication systems. The changes apply to new models that you create later in the MATLAB^® session, but not to previously created models.

Note   The Signal Processing Blockset™ application includes a similar dspstartup script, which assigns different model settings. For modeling communication systems, you should use commstartup alone.

To install the communications-related model settings each time you start MATLAB, invoke commstartup from your startup.m file.

To be more specific, the settings in commstartup cause models to:

• Use the variable-step discrete solver in single-tasking mode

• Use starting and ending times of 0 and Inf, respectively

• Avoid producing a warning or error message for inherited sample times in source blocks

• Set the Simulink Boolean logic signals parameter to Off

• Avoid saving output or time information to the workspace

• Produce an error upon detecting an algebraic loop

• Inline parameters if you use the Model Reference feature of Simulink
