dspstartup

Configure the Simulink environment for DSP systems

Syntax

• dspstartup
  

Description

dspstartup configures a number of Simulink environment parameters with settings appropriate for a typical DSP project. When the Simulink environment has successfully been configured, the function displays the following message in the command window.

• Changed default Simulink settings for DSP systems (dspstartup.m).
  

To automatically configure the Simulink environment at startup, add a call to dspstartup.m from your startup.m file. 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.m, and save the file as startup.m. The result should look like this.

• %STARTUP Startup file
  %   This file is executed when MATLAB starts up, 
  %   if it exists anywhere on the path. 
  dspstartup;
  

For more information, see the description for the startup command in the MATLAB documentation, Using dspstartup.m.

The dspstartup.m script sets the following Simulink environment parameters. See Appendix A, "Model and Block Parameters," in the Simulink documentation for complete information about a particular setting.

Parameter	Setting
SingleTaskRate TransMsg	error
Solver	fixedstepdiscrete
SolverMode	SingleTasking
StartTime	0.0
StopTime	inf
FixedStep	auto
SaveTime	off
SaveOutput	off
AlgebraicLoopMsg	error
InvariantConstants	on
RTWOptions	[get_param(0,'RTWOptions')', -aRollThreshold=2']
