✨ dlarnd — the random-number bestie ✨

okay so this page is TESTING/MATGEN/dlarnd.f(3), and it lives in the Library Functions Manual. it’s giving “tiny Fortran function, big main character energy” 💅

🌸 NAME 🌸

TESTING/MATGEN/dlarnd.f — literally the file, bestie.

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

• double precision function dlarnd (idist, iseed) — DLARND 👑

🫶 Function/Subroutine Documentation 🫶

double precision function dlarnd (integer idist, integer, dimension( 4 ) iseed)

DLARND

💖 Purpose 💖

DLARND returns a random real number from a uniform or normal distribution. no cap, that’s the whole glow-up ✨

🌸 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, this is 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. slay, but keep it odd bestie 🔥
