MATLAB: Return variable of Sim() command

m-fileMATLABsimulink

simout=sim('mymodel','AbsTol', '1e-5','SaveState','on','StateSaveName','xoutNew','SaveOutput','on', 'OutputSaveName','youtNew');

using this command but getting a error "TIMESPAN" should be real vector/scelor.

Best Answer

The syntax that you are using was introduced in R2009b. If you're using R2009a or an older release, the second parameter needs to be a timespan vector. Also, you need to use the Backwards Compatible Syntax.

This is a matter of the return variables of the SIM command. This examples code is from the documentation:

Specify parameter name-value pairs within the sim command:

simOut = sim('vdp','SimulationMode','rapid','AbsTol','1e-5',...
          'SaveState','on','StateSaveName','xoutNew',...
          'SaveOutput','on','OutputSaveName','youtNew');

Important is, that you need - like in this example - an "out" Block at the end of the relevant signal(s).

You need to use the Data Import/Export Pane of the model's Configuration Parameters window to get data using the Inport block. See Importing Data to Root-Level Input Ports for more information.
