TESTING/MATGEN/zlarnd.f(3) 💅

okay bestie, welcome to the Library Functions Manual page for TESTING/MATGEN/zlarnd.f — yes, the title is right there, and we are gonna get through it together. This one is short and iconic: it’s all about zlarnd, a function that pulls random complex numbers. no cap. 🎀

✨ NAME ✨

The name of this page is TESTING/MATGEN/zlarnd.f. slay. 🦋

✨ SYNOPSIS ✨

Functions/Subroutines

• complex *16 function zlarnd (idist, iseed) — the one and only, bestie; it’s labeled ZLARND in the docs. 💖

📚 Function/Subroutine Documentation

🌈 complex*16 function zlarnd (integer idist, integer, dimension( 4 ) iseed)

ZLARND

💖 Purpose:

ZLARND returns a random complex number from a uniform or normal distribution. That’s it, that’s the purpose, and it ate. 😭✨

🎀 Parameters

• IDIST — IDIST is INTEGER. It specifies the distribution of the random numbers, and the options are:
  • = 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, 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. periodt. 🔥

🧚 Further Details:

This routine calls the auxiliary routine DLARAN to generate a random real number from a uniform (0,1) distribution. The Box-Muller method is used to transform numbers from a uniform to a normal distribution. iykyk 💜
