i'm not sure how to write this since i'm new to matlab!
Write a function that receives a number n and determine if it is a prime number (output 1) or not (output 0). You can not use the ‘isprime’ function.

Do you know how to test whether a number is prime? Here is one way you can start:
  1. Generate numbers between 2:(n/2)
  2. Test if n is divisible by any of those numbers (eg mod())
  3. Return appropriately based on #2.

You do not need to go as far as n/2, you can stop at sqrt() of the number
