How can I use function handles in Simulink?

Hello,

i found similar questions, but none did account for my problem in Simulink.

I have a function handle in my model workspace, and I want to use it as a function in the model.

How can I use the function handle in the model workspace, to compute an output by the given input?

The function in the workspace has this shape:

y = @ (t) f(t);

With f beeing a function a compute in a different script which could change.

Looking forward to any Help :)

I had the same problem and I found this method using the symbolic math toolbox and Simulink Interpreted MATLAB Fcn block that works :

Thank you very much! That is exactly what I was looking, for.

Neverthenless kinda strange that function handles dont function with simulink. Is there any better way to use a changing function in Simulink?
