MATLAB: Gmake: *** Error 1 when attempting to run Simulink with embedded Matlab Function

gmakematlab codermexsimulink

I am trying to run a Simulink model that has an embedded matlab function using the Pwelch function. However I get this error during the make process and I have no idea what the cause of the error is. Can you help?

Best Answer

The source of the problem was found to be size limitations placed on the port dimensions for some signals in 'Model Explorer'. In some cases these limitations were being exceeded. It is a real challenge working with Variable-size signals within a Simulink Model that uses embedded Matlab functions.
Code size was not an issue.
