I need a small help in S-Function development.
I am trying to write an S-Function, which takes an input , which is a matrix of [5][400].
The inputs will be updated for every cycle.
I am able to generate .mexw32 file, but MATLAB is crashing while running the same using S-Function block in Simulink.
I feel, there are some bugs in my S-Function Program .
Can someone help me in analyzing that.
I will share you my S-Function, that i wrote.

Hi,
the documentation describes how to debug mex files. One thing that is definitely missing is to declare direct feedthrough for the input port (use ssSetInputPortDirectFeedThrough for the input port).
