Code:

void vector_copy(double *vector1, int vector_width, double **vector2)
{
        int i;

        if(vector_width > MAX_VECTOR_WIDTH) {
                fprintf(stderr, "vector_width greater than MAX_VECTOR_WIDTH\n");
                fprintf(stderr, "Please increase MAX_VECTOR_WIDTH in vector_lib.h and recompile.\n");
                exit(-1);
        }

        for(i = 0; i < vector_width; i++){
                (*vector2)[i] = vector1[i];
        }
        return;
