Program name: vector_add

Language: C

In file: vector_lib.c

Objective: Add a vector to another

Usage: void vector_add(double *vector1, int vector_width, double **vector2);

Parameters:

• vector1 - The pointer to the first input vector array
• vector2 - The pointer to the second input vector array
• vector_width - Number of elements in each vector
• vector3 - The pointer to the output vector array address

• void

Mathematical Description: v1 + v2 ==> v3

Comments: Routine is used to add a vector to another

Code:

void vector_add(double *vector1, double *vector2, int vector_width, double **vector3)
{
        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++){
                (*vector3)[i] = vector1[i] + vector2[i];
                number_adds++;
        }
        return;
