How call a matlab function in the c compiled library in python?

Hello

I'd like to write the code calling the matlab function from shared c library.

But when I call the function in the python using ctype library, I immediately got an error by the segmentation fault.

I don't know what's wrong with it and I'm not even know if it's possible or not.

Do you have any example code?

What I'm trying to do is like this code below.

import ctypes
cdll = ctypes.cdll.LoadLibrary("myLib.so")
if not cdll.myLibInitialize() :
    print "** Error : library is not initiallized ..."
    exit
else :

    
    freturn = ctypes.c_char_p("temp.mat")
    ptr_freturn = ctypes.pointer(freturn)
    arg = ctypes.c_int(9)
    ptr_arg= ctypes.pointer(arg)
    cdll.mlfTest_func(1, ptr_freturn , ptr_arg)

Hello Seyoung

In order to use a MATLAB function in Python, MathWorks offers Python Package integration through the MATLAB Compiler SDK the documentation for which can be found here:
