Function/Subroutine Documentation

subroutine dlarnv (integer IDIST, integer, dimension( 4 ) ISEED, integer N, double precision, dimension( * ) X)

DLARNV returns a vector of random numbers from a uniform or normal distribution.  

Purpose:

 DLARNV returns a vector of n random real numbers from a uniform or
 normal distribution.
Parameters:

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.

N

          N is INTEGER
          The number of random numbers to be generated.

X

          X is DOUBLE PRECISION array, dimension (N)
          The generated random numbers.

Further Details:

  This routine calls the auxiliary routine DLARUV to generate random
  real numbers from a uniform (0,1) distribution, in batches of up to
  128 using vectorisable code. The Box-Muller method is used to
  transform numbers from a uniform to a normal distribution.
