call mexfile from sfunction

Hi how can I call a mex-file in an S-Function Builder in simulink? I find a mex-file in the internet and don't know about its source code. this mex-file hase several inputs argumant and several outputs. I wanna to use it in my sfunction, but donn't know how can I do it.

Hi,

at least a mexCallMATLAB from the S-function should work. Or also runtime dynamic linking. See my post here:

Or just write a MATLAB S-function, and call your MEX-file like you would any other MATLAB function.

dear Kaustubha, I wanna write a C++ cod using "S-Function Builder" in simulink. I'm an amateur user, and thought can't use MATLAB function in "S-Function builder". Can I?

[Kaustubha Govind]

Omid: No, if you absolutely need a C-MEX S-function that is auto-generated using S-function Builder, then please follow Friedrich's solution. However, if there is no other C code that you need to call and you are okay with manually implementing a MATLAB S-function, you may follow my solution.

I understand, tanks for your help.
