Write a program to find the norm of a matrix

norm: square root of sum of square element of a matrix

#include<stdio.h> #include<math.h> int main() { float a[5][5],sum=0; int row,column,i,j; printf("Enter matrix size.\n"); scanf("%d%d",&row,&column); printf("Enter elements in array:\n"); for(i=0;i<row;i++){ for(j=0;j<column;j++){ printf("a[%d][%d]=",i,j); scanf("%f",&a[i][j]); sum+=a[i][j]*a[i][j]; } } sum = sqrt(sum); printf("Result = %f",sum); return 0; }

**Output**

Enter matrix size.

2

2

Enter elements in array:

a[0][0]=1

a[0][1]=2

a[1][0]=3

a[1][1]=4

Result = 5.477226
