MATLAB: Initialize MATLAB-Function

Question

Hello

I've read in the previous questions, that initializing a MATLAB-Function in Simulink is done like:

    persistent j;
    if isempty(j)
        j = 1;
    end   

And I have done so. Then I use the value j.

The problem is, as I want to run the simulink model, I get the following error:

Any ideas how to solve this problem?

Thanks.

This is not really an error. It just tells that you need to change the sampling rate of this block from continuous to discrete. Just click the "Fix" button on the first box under "Suggested actions" and the error will be fixed.
