DLARUV(3)

💖 NAME

okay bestie, the manual page name is dlaruv.f(3), and this whole page is about the file /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/dlaruv.f. slay. 💅

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine DLARUV (iseed, n, x) — DLARUV returns a vector of n random real numbers from a uniform distribution. 🎀

🦋 Function/Subroutine Documentation

subroutine DLARUV

The full signature is literally this:

subroutine DLARUV (integer, dimension( 4 ) iseed, integer n, double
    precision, dimension( n ) x)

Purpose

DLARUV returns a vector of n random real numbers from a uniform (0,1) distribution, and the cap is n <= 128. no cap. okay there is a cap, bestie, it's 128.

It's an auxiliary routine called by DLARNV and ZLARNV. 🫶

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. periodt.

X

X is DOUBLE PRECISION 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). iykyk. 🌈

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. iconic. ⭐
