💖 NAME 💖

okay so bestie, we're on the dlaran.f(3) page from the Library Functions Manual, and the file this whole thing is about is:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/MATGEN/dlaran.f

The function is DLARAN and it's giving random-number generator energy. lowkey iconic. ✨

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

double precision function DLARAN (iseed)

DLARAN — that's the short label, and the signature is right there, bestie. periodt.

🫶 Function/Subroutine Documentation 🫶

Here's the full signature with the array dimension, no cap:

double precision function DLARAN (integer, dimension( 4 ) iseed)

DLARAN — again, that's the function name. iconic. 👑

🌸 Purpose 🌸

DLARAN returns a random real number from a uniform (0,1) distribution. slay. 💅

🍓 Parameters 🍓

• 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. 🔄

🔥 Further Details 🔥

This routine uses a multiplicative congruential method with modulus 2**48 and multiplier 33952834046453 (see G.S.Fishman, 'Multiplicative congruential random number generators with modulus 2**b: an exhaustive analysis for b = 32 and a partial analysis for b = 48', Math. Comp. 189, pp 331-344, 1990).

48-bit integers are stored in 4 integer array elements with 12 bits per element. Hence the routine is portable across machines with integers of 32 bits or more. 🌈
