subroutineclarnv(integeridist,integer,dimension(4)iseed,integern,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. ParametersIDIST 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 array, dimension (N) The generated random numbers. Author Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. FurtherDetails: 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. subroutinedlarnv(integeridist,integer,dimension(4)iseed,integern,doubleprecision,dimension(*)x)DLARNV returns a vector of random numbers from a uniform or normal distribution.
