Simulating C MEX S-Function causes crash (Level 2)

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).
