I need help writing a program that finds all the twin primes between 10 and 500 without using a built in function.

Brendon - suppose you had a set of all numbers from 10 through to 500. Given the definition of a prime number, which of those numbers in this set can you (easily) eliminate first?
The even numbers or all those that are a multiple of two. What numbers could you try to eliminate next? Etc.

Take a look at http://en.wikipedia.org/wiki/Sieve_of_Eratosthenes. I'm sure someone must have coded this up in MATLAB and probably uploaded it to the File Exchange.
