🦋 DETAILED DESCRIPTION 🦋

okay so the full breakdown is right below in Function Documentation, bestie — no thoughts, just routines, seeds, and random-number glam. ✨

✨ FUNCTION DOCUMENTATION ✨

💖 clarnv 💖

   subroutine clarnv (integer idist, integer, dimension( 4 ) iseed, integer n,
       complex, dimension( * ) x)

Purpose: CLARNV returns a vector of n random complex numbers from a uniform or normal distribution. iconic behavior. 🦋

Parameters:

  • IDIST — 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 — 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 — INTEGER. The number of random numbers to be generated.
  • X — COMPLEX array, dimension (N). The generated random numbers.
bestie, please clock the seed rules: elements between 0 and 4095, and ISEED(4) must be odd. the random-number gods said what they said. 💅

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.

💜 dlarnv 💜

   subroutine dlarnv (integer idist, integer, dimension( 4 ) iseed, integer n,
       double precision, dimension( * ) x)

Purpose: DLARNV returns a vector of n random real numbers from a uniform or normal distribution. slay. ✨

Parameters:

  • IDIST — INTEGER. Specifies the distribution of the random numbers:
    • = 1: uniform (0,1)
    • = 2: uniform (-1,1)
    • = 3: normal (0,1)
  • ISEED — 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 — INTEGER. The number of random numbers to be generated.
  • X — DOUBLE PRECISION array, dimension (N). The generated random numbers.

ngl, the zlarnv further-details line says DLARUV, and we are keeping it exactly as written. iykyk. 💀
