MATLAB: Trying to display a list of numbers

Question

I am trying to display a list of numbers of prime numbers from 1-1000. I tried using a for loop and if else statements.

for n=1:1000
    if rem(n,2) == 0
        disp('Not a prime number')
    elseif rem(n,3) == 0
        disp('Not a prime number')
    elseif rem(n,5) == 0
        disp('Not a prime number')
    elseif rem(n,7) == 0
        disp('Not a prime number')
    elseif rem(n,11) == 0
        disp(num2str(n))
    end
end

Answer 1

Why not

primes(1000)

or isprime(): https://www.mathworks.com/help/matlab/ref/isprime.html in a for-loop.
