Write a function that takes a matrix with m rows and n columns as an input.

It should modify the matrix in the following ways: set all inputs to $0$

$-$ When the row number is greater than the column number, replace the element with the column index.

$-$ When the column number is greater than the row number, replace the element with the row index.

$-$ When column number is equal to row number, divide the element by the numerical component of your netid.

This modified matrix should be the output of your function.
