How can I acces Data from Simulink when the model gets called in a function?

Hello,

I have written a GUI and the callback of a button is a function that saves input and starts a simulink model.

I would like to get back the resulting data to the GUI to plot them, right now I have to use a scope block and switch between windows.

But the "To Workspace" Block and the logging function of the scope both only work when I press play directly in Simulink.

It does not work when I use the "sim" command in the nested function, even if I initialize the variables before the function.

Just nothing happens.

Can anybody give me a hint how to work around this problem?

Thank you!

How is it that you are doing it? To test it I made a simulink function with a "To Workspace" block and accessed it in a function as such:

function letsTest()
simout = sim('myModel');
figure;
plot(myData.Time,myData.Data)

This seemed to work fine which would also imply to me that I could use that data and return that data as desired. My save format for the simulink block is time series in case that might matter.
