4. A perfect number is a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Write a Matlab program that is not a function that will take a number and determine if it is a perfect number. The program should respond with a compete sentence. For example, if the given number is 5, the program should return the statement, The number 5 is not a perfect number. Note you will need to use some of the functions we made in class today (11/2). (Turn in the script, a diary of the program running for at least two examples.)
