for f = (1:100)
f
isprime(f)
j = all(f)
end
fprintf('%j',j)
This is what I have, I either get j as logical or if I change it to "fprintf('%f', f)" I get f = 100.
I need to print the prime numbers.
What am I doing wrong?

num = 1:100 ; % numbers till 100
idx = isprime(num) ; % get logical indices of prime numebrs
num(idx) % print the prime numbers

The square brackets here are completely superfluous:
primenum = [num(idx)]
Get rid of them, they do absolutely nothing.
