Communications Blockset

commstartup

Default Simulink model settings for Communications Blockset

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 DSP Blockset 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 ode45 (Dormand-Prince) solver, which is a variable-step solver
• Default to a fixed step size and SingleTasking mode, in case you change the solver manually to a fixed-step solver
• Use starting and ending times of 0 and Inf, respectively
• Avoid saving time or output information to the workspace
• Produce an error upon detecting an algebraic loop
• Inline parameters and use a loop rolling threshold of 5, in case you use the Real-Time Workshop® to generate code from the model
