I want to know if I can call an embedded Matlab function defined in my Simulink model from the Matlab command line. I'd like to have a unit test for each function, without having to run the simulation. Is there a way to do this?

The code for the MATLAB Function block does not exist as a stand-alone file that you can call in MATLAB. However, you can programatically get the code in MATLAB as a string using the steps in Answer 102675. From there, you could write the text to a file and then call it.

This worked. Thank you! Just to summarize what I did:

- S = sfroot;

- B = S.find('Name','my_embedded_matlab_function');

- fid = fopen('test_function.m,'w');

- fprintf(fid,'%s',B.Script');

- fclos(fid);

Please be aware that Simulink generates code from MATLAB Function blocks for faster execution. When you test the same function in MATLAB, you are running it using the MATLAB interpreter. Please know that there may be Differences in Behavior After Compiling MATLAB Code when using fixed-point data. In such cases, the safe thing to do would be to call the Simulink model using the SIM command to test.
