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

Function/Subroutine Documentation

subroutine slarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, real, dimension( * )X)

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

Purpose:

SLARNV 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 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 Box-Muller method is used to
transform numbers from a uniform to a normal distribution.
