Write a MATLAB function (testPrime.m) that takes a scalar as an input argument and uses a for-loop and rem function to check whether the argument is a prime number. testPrime(x) should return 1 if x is a prime number and 0 otherwise. Your testPrime function must behave as shown below: (user input is underlined) >> help testPrime testPrime(n) determine whether n is a prime number return true (1) if n is prime return false (0) if n is not prime >> testPrime(12) ans = logical 0

>> testPrime(7) ans = logical 1 Hint: To get a logical 1 and logical 0 as output of your function, see "help true" and "help false".
