Hi,
the content in your .mat-file has to be saved as a timeseries object. See this example how to create this.
Your function has to take as many input arguments as signals you want to connect in your model:
.
function y = fcn(u,t)
y = 3*cos(u*t);
end
If you want to pass time and data from .mat-file, change your funtion the way shown in the above example. If your function is defined in this way you can connect both signals in Simulink:
.
But be careful - See the result of this:
.
This is the result, due to the input is a timeseries - the time information is in the .mat-file. I attached a .matfile as example which contains a timeseries object for t=0...10 in 100 steps and the data is from -2*pi...2*pi in 100 steps. See what happens if we diconnect t and change the function to:
function y = fcn(u)
y = 3*cos(u);
end
.
The model now:
.
So think about if you really need the time block for your model. Test the attached model.
Best regards
