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
ISEEDISEED 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.
NN is INTEGER The number of random numbers to be generated.
XX 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.
