Write a program to specify if a given positive integer is a prime number or not. Recall that a prime number can be divided only by 1 and by itself. You are NOT allowed to use the MATLAB predefined function isprime in solving this problem. Hint. To solve this problem, you should follow the steps below. Step 1. Ask the user to enter a positive integer (e.g. n). Do not forget to check if the number entered is, in fact, a positive integer. Step 2. Create a while-end loop to check if n can be divided by any of the numbers from 2 to n - 1. Use the MATLAB function rem to find the remainder of n divided by any of the numbers from 2 to n - 1
