PRIME

PRIME

Name


    PRIME

Purpose


    Return an array with the specified number of prime numbers.
  EXPLANATATION:
    This procedure is similar to PRIMES in the standard IDL distribution,
    but stores results in a common block, and so is much faster

Calling Sequence


      p = prime(n)

Inputs


      n = desired number of primes, scalar positive integer

Outputs


      p = resulting array of primes, vector of positive integers

Common Blocks


      prime_com

Notes


      Note: Primes that have been found in previous calls are
        remembered and are not regenerated.

Modification History

      R. Sterner, 5 Feb, 1993 --- fixed a bug that missed a few primes.
      Converted to IDL V5 March 1999
