DLASRT(3)

📦 version 3.12.0, in opensuse-leap 16.0

okay bestie, welcome to DLASRT(3) from the Library Functions Manual 💅 this is the page for the routine that sorts numbers, and yes it’s giving main character energy.

🌸 NAME 🌸

this page is literally about /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/dlasrt.f — that’s the whole NAME section, no cap.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

  • subroutine DLASRT (id, n, d, info) — DLASRT sorts numbers in increasing or decreasing order. slay.

💖 Function/Subroutine Documentation 💖

subroutine DLASRT (character id, integer n, double precision, dimension( * )
       d, integer info)

DLASRT sorts numbers in increasing or decreasing order. periodt.

🌟 Purpose 🌟

so the whole point, bestie: sort the numbers in D in increasing order if ID = 'I', or in decreasing order if ID = 'D'. it uses Quick Sort, but reverting to Insertion sort on arrays of size <= 20. also, heads up: the dimension of STACK limits N to about 2**32. that’s the vibe.

🎀 Parameters 🎀

🦋 ID 🦋

ID is CHARACTER*1.

  • = 'I': sort D in increasing order;
  • = 'D': sort D in decreasing order.

🦋 N 🦋

N is INTEGER. it’s the length of the array D.

🦋 D 🦋

D is DOUBLE PRECISION array, dimension (N).

on entry, it’s the array to be sorted. on exit, D has been sorted into increasing order (D(1) <= ... <= D(N) ) or into decreasing order (D(1) >= ... >= D(N) ), depending on ID.

🦋 INFO 🦋

INFO is INTEGER.

  • = 0: successful exit
  • < 0: if INFO = -i, the i-th argument had an illegal value
