MATLAB QUESTION: Write a script that prompts the user to enter two numbers M and N. The script shoud then create a M-by-N matrix of random numbers (use rand). Use nested for loops to move through the matrix, element by element, and set any value that is less than 0.2 to 0 and any value that is greater than (or equal to) 0.2 to 1. Display the original matrix and edited matrix to the command window. Test your code with M = 4 and N = 3

(Please explain the lines of the code a little)
