printf("\nEnter the row and column of first matrix");
scanf("%d %d",&m,&n);
printf("\nEnter the row and column of second matrix");
scanf("%d %d",&o,&p);
if(n!=o){
printf("Matrix mutiplication is not possible");
printf("\nColumn of first matrix must be same as row of second matrix");
}
else{
printf("\nEnter the First matrix->");
for(i=0;i<m;i++)

return 0;
}

Alogrithm:

Multiplication of two matrixes:

Rule: Multiplication of two matrixes is only possible if first matrix has size m X n and other matrix has size n x r. Where m, n and r are any positive integer.

Multiplication of two matrixes is defined as

Where 1 i  m and 1 ≤ j  n

For example:
Suppose two matrixes A and B of size of 2 x 2 and 2 x 3 respectively:

thanks vasant said...

nice one ... was asked this in an interview where I goofed up ...good logic

Mudasir Mohi ud din said...

Matrix multiplication-prove using c prog multiplication is possible only if(r1==c2) and the order of resultant matrix will be c1*r2

Mudasir Mohi ud din said...

Broad cocept of multiplication of matrices
