NAME
dlarnv.f -

SYNOPSIS
Functions/Subroutines
subroutine dlarnv (IDIST, ISEED, N, X)
DLARNV returns a vector of random numbers from a uniform or normal distribution.

Function/Subroutine Documentation
subroutine dlarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, 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.
