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

## Function/Subroutine Documentation

 subroutine clarnv ( integer IDIST, integer, dimension( 4 ) ISEED, integer N, 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:
 [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.```
Date:
September 2012
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.```
