SYNOPSIS¶
Functions/Subroutines¶
subroutine zlarnv (IDIST, ISEED, N, X)
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.
