SYNOPSIS
Functions/Subroutines
subroutine clarnv (IDIST, ISEED, N, X)
CLARNV returns a vector of random numbers from a uniform or normal distribution.
Function/Subroutine Documentation
subroutine clarnv (integerIDIST, integer, dimension( 4 )ISEED, integerN, complex, dimension( *
)X)
CLARNV returns a vector of random numbers from a uniform or normal distribution.
Purpose:
CLARNV returns a vector of n random complex numbers from a uniform or
normal distribution.
Parameters:
IDIST
IDIST is INTEGER
Specifies the distribution of the random numbers:
= 1: real and imaginary parts each uniform (0,1)
= 2: real and imaginary parts each uniform (1,1)
= 3: real and imaginary parts each normal (0,1)
= 4: uniformly distributed on the disc abs(z) < 1
= 5: uniformly distributed on the circle abs(z) = 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 COMPLEX 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.
