🦋 SLARUV(3) 🦋

okay so bestie, you're reading the SLARUV(3) page from the Library Functions Manual — the path is literally /home/abui...RC/slaruv.f(3) at both ends of the original header, iconic. Let's get into it 💅

That's the file, no cap. 🫶

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine SLARUV (iseed, n, x)

SLARUV returns a vector of n random real numbers from a uniform distribution. slay. 💖

📚 Function/Subroutine Documentation 📚

subroutine SLARUV (integer, dimension( 4 ) iseed, integer n, real, dimension( n ) x)

SLARUV returns a vector of n random real numbers from a uniform distribution. Yes, literally that. 🔥

🎀 Purpose 🎀

ok so the purpose is: SLARUV returns a vector of n random real numbers from a uniform (0,1) distribution, with n <= 128. It's an auxiliary routine called by SLARNV and CLARNV. That's the whole vibe. ✨

🌸 Parameters 🌸

  • ISEED — ISEED is INTEGER array, dimension (4). On entry, it's 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. It's the number of random numbers to be generated. N <= 128. 🔢
  • X — X is REAL array, dimension (N). These are the generated random numbers. 🎲

🧚 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. portability queen 💅
