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. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Date: September 2012 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. Definition at line 98 of file dlarnv.f.
