Matlab program to find prime numbers: first hundered if n = 100

n = 103; numbers = 2: n; primes = []; for i = 1: length(numbers) if ~ numbers(i) == 0 for j = i+1: length(numbers) if rem(numbers(j), numbers(i)) == 0 numbers(j) = 0 end end end if ~ numbers(i) == 0 primes(length(primes) + 1) = numbers(i) end end primes
