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

## Function/Subroutine Documentation

### subroutine zlarnv (integer IDIST, integer, dimension( 4 ) ISEED, integer N, complex*16, dimension( * ) X)

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.```
