Example Matrices

matrix_a = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
print ("Matrix a is :",matrix_a)
matrix_b = [[9, 8, 7], [6, 5, 4], [3, 2, 1]]
print ("Matrix b is :",matrix_b)

a) Addition of two matrices

addition_result = add_matrices(matrix_a, matrix_b)

b) Subtraction of two matrices

subtraction_result = subtract_matrices(matrix_a, matrix_b)

c) Multiplication of two matrices

multiplication_result = multiply_matrices(matrix_a, matrix_b)

d) Transpose of a matrix

transpose_result_a = transpose_matrix(matrix_a)
transpose_result_b = transpose_matrix(matrix_b)
