Purpose:

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

Parameters:

[in]	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
[in,out]	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.
[in]	N	N is INTEGER The number of random numbers to be generated.
[out]	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 Box-Muller method is used to
  transform numbers from a uniform to a normal distribution.
