How to implement the library

Use the library as any other library in your system

/** main.c
 * This programs makes the matrix multiplication of a and b
 * and stores the result in the result variable
 */
#include <ddcc.h>
#include <stdio.h>

int main() {
    float **a, **b, **result;
    int x=5, y=5;

    a = (float**)malloc(sizeof(float*)*x);
    b = (float**)malloc(sizeof(float*)*x);
    result = (float**)malloc(sizeof(float*)*x);
    for (int i = 0; i < x; ++i) {
        a[i] = (float*)malloc(sizeof(float)*y);
        b[i] = (float*)malloc(sizeof(float)*y);
        result[i] = (float*)malloc(sizeof(float)*y);
        for (int j = 0; j < y; ++j) {
            a[i][j] = (float)i+j;
            b[i][j] = (float)i-j;
        }
    }

    ddccMatrixMultiplication(a, x, y, b, x, y, &result);
    return 0;
}

Building the library

gcc stand alone

gcc main.c -o matrix.out -lddcc
