Calling Simulink model in a function

Hello,

I have a Simulink model using the variable V in a gain block. I want to perform a parameter analysis and therefor have to start the simulation several times with the command sim.

This works fine if I do this in the command window or using a script.

If I call sim in a function, and the parameter V for the model is an argument of the function, the model will not recognize the variable inside the function. Can someone give me explantion for this behaviour?

Simulink uses the base workspace. You can assign the variable in the base workspace using assignin or evalin.

Alternatively, you can set up your model to accept a time series input and supply that from your function.
