I would like a walk through on how to develop a python ver 3.x based application. This application must allow a user to enter the values of two 3X3 matrices and then select from any of the following options. Addition, subtraction, matrix multiplication, as well as element by element multiplication. I am trying to see how numpy.matmul() works for matrix multiplications. This is also known as np.matmul(a,b). Then end goal of the program should be able to compute the appropriate results, return the results, as well as transpose those results, provide the mean of the rows for the results, and finally the mean for each column of the results. The program will need a check used to ensure that the values getting entered by the user for the matrices are in fact numeric. (no letters) Also the user interface will need to continue to run until the user indicates they are ready to exit the program. Please document every step of the way. I am reading through the steps in a book and they aren't outlining it well for me and seeing this being done will help me to build my own program. A rough outline of how the output of the program should look can be found below.

Select a Matrix Operation from the list below:

a. Addition

b. Subtraction

c. Matrix Multiplication

d. Element by element multiplication

a

You selected Addition. The results are:

4 4 5

11 4 6

8 10 10

The Transpose is:

4 11 8
