Subtraction Of Two Matrix.

SUBTRACTION OF TWO MATRICES USING ARRAY  C++ PROGRAM And ALGORITHM 

Algorithm

Subtraction of two matrixes:

Rule: Subtraction of two matrixes is only possible if both matrixes are of same size.

Suppose two matrixes A and B is of same size m X n

Subtraction of two marixes is defined as

(A - B)_ij  = A_ij - B_ij

Where 1 ≤ i ≤ m and 1 ≤ j ≤ n

For example:

Suppose two matrixes A and B of size of 3 X 2 is as follow:

#include<iostream.h>

#include<conio.h>

#include<stdio.h>

#include<iomanip.h>    // for setw()

int main()

{

int m1[10][10],m2[10][10],add[10][10],i,j,r1,c1,c2,r2;

clrscr();

start:

cout<<"Enter how row and column you wants in matrix 1:\n";

cin>>r1>>c1;

cout<<"Enter how row and column you wants in matrix 2:\n";

cin>>r2>>c2;

if(r1!=r2 || c1!=c2)

{

cout<<"Enter same m*n matrixs.\n";

goto start;

}

cout<<"Enter for first matrix:\n";

for(i=0;i<r1;i++)

{

for(j=0;j<c1;j++)

{

cin>>m1[i][j];

}

}

cout<<"Enter for sencond matrix:\n";

for(i=0;i<r2;i++)

{

for(j=0;j<c2;j++)

{

cin>>m2[i][j];

}

}

for(i=0;i<r1;i++)

{

for(j=0;j<c1;j++)

{

add[i][j]=m1[i][j]-m2[i][j];

}

}

cout<<"The Substraction of matrix is:\n";

for(i=0;i<r1;i++)

{

cout<<endl;

for(j=0;j<c1;j++)

{

cout<<setw(5)<<add[i][j];

}

}

getch();

return 0;

}
