Malloc a 3-Dimensional array in C?

Question

I\'m translating some MATLAB code into C and the script I\'m converting makes heavy use of 3D arrays with 10*100*300 complex entries. The size of the array also depends on t

Answer 1

#include
#include

#define MAXX 3
#define MAXY 4
#define MAXZ 5

main()
{
int ***p,i,j;
p=(int ***) malloc(MAXX * sizeof(int **));

for(i=0;i < MAXX;i++)
{
p[i]=(int **)malloc(MAXY * sizeof(int *));
for(j=0;j < MAXY;j++)
p[i][j]=(int *)malloc(MAXZ * sizeof(int));
}

for(k=0;k < MAXZ;k++)
for(i=0;i < MAXX;i++)
for(j=0;j < MAXY;j++)
p[i][j][k]= < something >;

}
