MATLAB PROGRAMMING ONLY

I am having a hard time understanding persistent variables and how exactly to code this. I have watched countless videos and am still unable to understand this problem. If you could please explain the code step by step that would be greatly appreciated. Thank you!

Please be aware: The function must make use of a persistent variable.

How many times divide by zero? Write a function Divide that divides two numbers, and keep count of how many times the function was called asking to divide by zero. The function has two output, the division of the two numbers and the number of times the function was called with a divide-by-zero request. In the case of a divide-by-zero request, the resultant should be set to not a number. The function must make use of a persistant variable. For example: clear all; x=1; y=1; [z,times] Divide(x,y) = times = [1 x=1 ; y-0 ; [z,tines] Divide ( x, y) >> : NaN times = [z,times] = Divide (x,y) >> x=2 ; y:0; howmany- NaN times = Your Function Save Reset MATLAB Documentation function [z,times] Divide(x,y) =
