Question

Can you write me a python program that allows a user to enter and validate their phone number and zipcode+4. Then the user will enter values of two, 3x3 matrices and then select from options including, addition, subtraction,
matrix multiplication, and element by element multiplication. You should use numpy.matmul() for
matrix multiplication (e.g. np.matmul(a, b) ). The program should compute the appropriate results
and return the results, the transpose of the results, the mean of the rows for the results, and the
mean of the columns for the results.
