variables in Simulink Workspace

Hi,

I have created a variable 'simout' with the To Workspace block in Simulink. Now I have to use this in a m file, but an error indicates that 'simout' is not defined. How to import this in a m file?

Thanks Senmeis

If it's In workspace, means it's recognized by m file. check your to workspace block, then set save format to array

Simulink resolves variables from base workspace, so if you use simout from a function it wont be able to 'see' it because functions use their own workspace. The following link might help you.

My goal is, simulate a model with 'sim()' in an m file, but the variable 'simout' seems not to be defined in the m file, which is created by the To Workspace block.

I tried

assignin('base', 'my_simout', simout)

and

assignin('caller', 'my_simout', simout)

but it doesn't work. I think 'simset()' also won’t work.

I noticed that all the variables created by the 'To Workspace' block won't be seen in the Matlab Workspace if the simulation is started in an m file. Any ideas?

Thank Senmeis

Owen, Variables from to workspace block are seen by any m file, (except Functions). Check if your variable is simout and not Simout or any typo error. To be sur rename it 'x' for e.g

Oops, I meant to say that you need to use:

options=simset('SrcWorkspace','current','DstWorkspace','current');
sim('mymdl',[0 duration],options)

So that 'To Workspace' writes to the function workspace.
