MATLAB: Sorting Prime Numbers From an Array of Numbers, Into a New Array

Question

n = [1:1:100];

N = isprime(n);

NN=[];

for i = 1:1:100

if N(i)==1 %if N at a position is equal to 1, then it is a prime number

n(i) %Displays the integer at that position %Now that number needs to be stored in a new array

NN=n(i) %This just sets the new array equal to the prime number n(i), this doesn't store it. It is replaced on the next loop

end

end

I need to know how to make a new array filled with the prime numbers from the loop

Answer 1

Why not use the primes function?

NN=primes(100);
