Subtract Two Matrices in Python

To subtract two matrices in python, first choose three matrices. First matrix, second matrix, and third matrix (to store the subtraction result to the third/this matrix). Initially, all the content of the third matrix will be 0. In other word, initially third matrix is an empty matrix.

Python Programming Code to Subtract Two Matrices

Following python program shows the subtraction of one matrix from another matrix in python:

# Python Program - Subtract Two Matrices

matrix1 = [[10, 11, 12],
   [13, 14, 15],
   [16, 17, 18]]
matrix2 = [[1, 2, 3],
   [4, 5, 6],
   [7, 8, 9]]
rmatrix = [[0, 0, 0],
   [0, 0, 0],
   [0, 0, 0]]
for i in range(len(matrix1)):
    for j in range(len(matrix1[0])):
        rmatrix[i][j] = matrix1[i][j] - matrix2[i][j]
for r in rmatrix:
    print(r)

Subtraction of the two given matrix in above program can be calculated as:
