zlarnv.f -


subroutine zlarnv (IDIST, ISEED, N, X)
 
ZLARNV returns a vector of random numbers from a uniform or normal distribution.

ZLARNV returns a vector of random numbers from a uniform or normal distribution.
Purpose:
 ZLARNV 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*16 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.
