C Language (Matrix Multiplication)

MATRIX MULTIPLICATION IN C

The matrix array consisted with the help of Double dimension array and we can perform several types of operation such addition, subtraction, multiplication in matrix array.

MATRIX MULTIPLICATION IN C

Multiplication is differ from addition and subtraction in matrix array.

So lets have an example...

Suppose we want to calculate multiplication of 2 D Arrays (3x3)

C PROGRAM FOR MATRIX  MULTIPLICATION
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int a[3][3],b[3][3],c[3][3];
int k,i,j,sum=0;
printf("Enter values for A:\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
scanf("%d",&a[i][j]);
}}

printf("\nEnter values for B:\n");
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
scanf("%d",&b[i][j]);
}}

printf("\n\nValues of A\n");
for(i=0;i<3;i++)
{
printf("\n\n");
for(j=0;j<3;j++)
{
printf("\t%d",a[i][j]);
}}

printf("\n\nValues of B");
for(i=0;i<3;i++)
{
printf("\n\n");
for(j=0;j<3;j++)
{
printf("\t%d",b[i][j]);
}}

//Loops for mulipliation
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
sum=0;
for(k=0; k<3; k++)
{
sum=sum+a[i][k]*b[k][j];
}
c[i][j]=sum;
}}

printf("\n\nMultiplication of mattrix array\n");
for(i=0;i<3;i++)
{
printf("\n\n");
for(j=0;j<3;j++)
{
printf("\t%d",c[i][j]);
}}
getch();
}
