Download ZLARNV + dependencies [TGZ] [ZIP] [TXT]ZLARNV returns a vector of n random complex numbers from a uniform or normal distribution.
[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*16 array, dimension (N) The generated random numbers. 
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 BoxMuller method is used to transform numbers from a uniform to a normal distribution.
