if I define a dynamic matrix in a function, how can I define it as global
martix since I need to use it in other functions.
Thanks!
int **array1 = (int **)malloc(nrows * sizeof(int *));
how to do that?

1 Define a global variable
int **g_array;
2 let g_array = (int **)malloc(nrows * sizeof(int *));
3 Use it in other function
extern int **g_array;
