Producing 100 prime number in a vector

Hi,

I want to generate a vector in which I could check that vector for prime numbers using isprime(vector). So far I have been able to get the get a vector, but it does not give the number which are prime. Instead it gives out a vector where all the prime numbers are replaced by one and non prime with zero.

p=(2:1:600)

y=isprime(p)

I used the following code.

Thanks in advance

[David Hill]

p=(2:1:600);
p(isprime(p))

ans = 1×109

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113

primes(600)%better and faster

ans = 1×109

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113
