CLARNV returns a vector of n random complex numbers from a uniform or


 normal distribution.

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.

  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.
