Please help me with these 3 matlab questions!

1. Write a MATLAB function with the header

function [M1, M2] = mySplitMatrix(M)

where M is a matrix, M1 is the left half of M, and M2 is the right half of M. In the case where there is an odd number of columns, the middle column should go to M1. Hint: the size and mod functions should be helpful.

(2) Write a MATLAB function with the header function [M] = myCheckerBoard(n) where M e RnXn has the following form: 1 01 0 1 and n is a positive integer. Note that the upper-left element should always be 1
