NAME
SLARNV  returns a vector of n random real numbers from a uniform or normal distribution
SYNOPSIS
 SUBROUTINE SLARNV(

IDIST, ISEED, N, X )

INTEGER
IDIST, N

INTEGER
ISEED( 4 )

REAL
X( * )
PURPOSE
SLARNV returns a vector of n random real numbers from a uniform or
normal distribution.
ARGUMENTS
 IDIST (input) INTEGER

Specifies the distribution of the random numbers:
= 1: uniform (0,1)
= 2: uniform (1,1)
= 3: normal (0,1)
 ISEED (input/output) 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 (input) INTEGER

The number of random numbers to be generated.
 X (output) REAL array, dimension (N)

The generated random numbers.
FURTHER DETAILS
This routine calls the auxiliary routine SLARUV to generate random
real numbers from a uniform (0,1) distribution, in batches of up to
128 using vectorisable code. The BoxMuller method is used to
transform numbers from a uniform to a normal distribution.
