Structure of Mat in opencv?

I tried Structure of Mat my app shows as "Run failed". Anyother way to do this?

The below is the code I tried and its getting failed. How to make this workout or anyother ways are there?

"Common.h"

struct initialize {
      cv :: Mat G_Sm;
};

"Initialize.cpp"

struct initialize* initfunction ( ) {
    struct initialize* initializemat = ( initialize* ) malloc(sizeof(*initializemat));
    initializemat -> G_Sm = Mat:: zeros ( 3,1, CV_8U );
    return (initializemat);
}

"main.cpp"

int main () { 
   struct initialize* initializem = initfunction ();
   cout << initializem -> G_Sm << endl;

 return 0;
}

Instead of Mat if I use "int" the program is not getting crashed. If it is "Mat" variable in the structure the program gets crashed.

Use C++ instead of C:

initialize* initfunction ( ) {
    initialize* initializemat = new initialize;
    return initializemat;
}

You shouldn't allocate C++ objects with malloc.
malloc doesn't call any constructors for you, leaving G_Sm uninitialised.
