Examples
gf_is_prime([0 1 2 9 97]) // [F F T F T] x = 1:30; x(gf_is_prime(x)) // primes up to 30 |  |  |
Tests whether integers are prime
tf = gf_is_prime(x)
Matrix of non-negative integers, smaller than 2^53.
Boolean matrix of the same size as x: T where the entry is prime.
gf_is_prime tests each entry of x by trial division. 0 and 1 are not prime. It can be used to check a characteristic before calling gf_create_field.
gf_is_prime([0 1 2 9 97]) // [F F T F T] x = 1:30; x(gf_is_prime(x)) // primes up to 30 | | |
