Hi at all, I have a problem when I run a simulink model inside a for loop.
More in detail when I run the model with the command:
set_param('model_name','SimulationCommand','start')
the script doesn't wait the end of the simulation before continue...
There some commands like the waitfor or the drawnow?
Thanks

Hi Mitch,
I would usually suggest to use the function sim for running simulations, or is there any reason you can't use sim?

Yes there is a reason but i dont now if it is right , the model save the date with the 'to workspace' block ... there is a very large numbers of variables stored and i dont want to change all the 'to workspace' blocks with the 'out' blocks.

You can use ToWorkspace blocks with sim: depending on the version of MATLAB you are running, the sim command has changed recently to make the use easier. But you can use
set_param(yourModel, 'DstWorkspace', 'current')
and then sim puts the results of the ToWorkspace blocks into your current workspace (inside your function e.g.).

I try but.....
??? Error using ==> set_param
block_diagram does not have a parameter named 'DstWorkspace'.
Error in ==> Main_more at 26
set_param('PID', 'DstWorkspace', 'current')
I use R2007b

Hi Mitch,
sorry, set_param was wrong, it's simset that you need to use
opt = simset('DstWorkspace', 'current');
and pass this to sim.
Sorry!

Fantastic... I dont need to open the model... I dont need to put a pause...All the variables are stored in the workspace with the correct name...
Thanks a lot Titus
