help! writing afunction for isprime

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.

Answer 1

[George]

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.

[Walter Roberson]

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

[George]

That's true.
