SLARND returns a random real number from a uniform or normal


 distribution.

IDIST

          IDIST is INTEGER


          Specifies the distribution of the random numbers:


          = 1:  uniform (0,1)


          = 2:  uniform (-1,1)


          = 3:  normal (0,1)

ISEED

          ISEED is INTEGER array, dimension (4)


          On entry, the seed of the random number generator; the array


          elements must be between 0 and 4095, and ISEED(4) must be


          odd.


          On exit, the seed is updated.

  This routine calls the auxiliary routine SLARAN to generate a random


  real number from a uniform (0,1) distribution. The Box-Muller method


  is used to transform numbers from a uniform to a normal distribution.
