MATLAB:

Design a SCRIPT which asks the user for a positive integer over 1 and then print outs all positive integer factors of that number as well as a statement of if the integer is prime or not. You can not use built in function for this other than fprintf and input. You must not allow your program to terminate unexpectedly, even if the user enters invalid input (i.e ask again until he gives valid input). Also FUNCTIONS (for our level) do not include any for of data validation.
