Program for subtracting two matrices.

To subtract two matrices −

• Create an empty matrix.
• At each position in the new matrix, assign the difference of the values in the same position of the given two matrices i.e. if A[i][j] and B[i][j] are the two given matrices then, the value of c[i][j] should be A[i][j] - B[i][j].

Example

 Live Demo

public class SubtractingMatrices{
   public static void main(String args[]){
      int a[][]={{1,2,3},{4,5,6},{7,8,9}};
      int b[][]={{1,1,1},{1,1,1},{1,1,1}};
      int c[][]=new int[3][3];
      for(int i=0;i<3;i++){
         for(int j=0;j<3;j++){
            c[i][j] = a[i][j]-b[i][j];
            System.out.print(c[i][j]+" ");
         }
         System.out.println();
      }
   }
}
