Matrix Substraction

Algorithm

Input Two matrices a and b       
Output Output matrix c  containing elements after subtraction of b from a  
complexity O(n^2)      
  
Matrix-Subtraction(a,b)  
1   for i =1 to rows [a]  
2      for j =1 to columns[a]  
3         Input a[i,j];  
4         Input b[i,j];  
5         C[i, j] = A[i, j] - B[i, j];  
6         Display C[i,j];  

Algorithm Description

To subtract two matrices sufficient and necessary condition is “dimension of matrix A = dimension of matrix B.” Loop for each row in matrix A. Loop for each column in matrix B. This loop will run for each rows of matrix A. Subtract B[i,j] from A[i,j] and store this value to C[i,j]; Return output matrix C.
