Operating a C++ class from Matlab without mex [closed]

Question:

Tag: c++,matlab

Is there an alternative way to call a C++ class using MATLAB, and operate its methods on MATLAB variables?


Answer:

You can use calllib to call functions in shared library.

This would be the newlib.h

#ifdef __cplusplus
extern "C"{
#endif
    void *init(int device);
#ifdef __cplusplus
}

#endif

and this would be the newlib.cpp file

#include "newlib.h"
#include "yourlib.h"

A *p;

extern "C" void *init(int device)
{
    p = new A;
    p->yourfunction(device);
}

then in Matlab

clc

LIB_NAME='libnewlib';
INC_NAME='newlib.h';

loadlibrary(LIB_NAME,INC_NAME);

device = 0;

calllib(LIB_NAME,'init', device);

unloadlibrary(LIB_NAME);

This has been working fine for me.
