okay bestie, this page comes from the Library Functions Manual, and it’s all about DLARNV — the LAPACK baddie that hands you random numbers 💅. No cap, every detail is right here.

✨ NAME ✨

SRC/dlarnv.f — literally the file, bestie. That’s the name 🎀.

✨ SYNOPSIS ✨

🧚 Function/Subroutine Documentation 🧚

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

DLARNV returns a vector of random numbers from a uniform or normal distribution. iconic behavior fr fr ✨

🍓 Purpose 🍓

DLARNV returns a vector of n random real numbers from a uniform or normal distribution.

💖 Parameters 💖

• IDIST — IDIST is INTEGER. It specifies the distribution of the random numbers:

= 1:  uniform (0,1)
= 2:  uniform (-1,1)
= 3:  normal (0,1)

• ISEED — ISEED is 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. periodt 🫶
• N — N is INTEGER. The number of random numbers to be generated.
• X — X is DOUBLE PRECISION array, dimension (N). The generated random numbers.

💀 Further Details 💀

This routine calls the auxiliary routine DLARUV 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. no cap, that’s the whole vibe 🔥
