This is the dlamrg.f(3) page from the Library Functions Manual — welcome to the group chat, bestie 💅

💖 NAME 💖

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/dlamrg.f — that's the file this page is documenting, periodt.

✨ SYNOPSIS ✨

🧩 Functions/Subroutines 🧩

  • subroutine DLAMRG (n1, n2, a, dtrd1, dtrd2, index) — DLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order. Slay.

📚 Function/Subroutine Documentation 📚

🛠️ The DLAMRG subroutine 🛠️

subroutine DLAMRG (integer n1, integer n2, double precision, dimension( * ) a, integer dtrd1, integer dtrd2, integer, dimension( * ) index)

DLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order. Iconic behavior, honestly.

🎯 Purpose 🎯

DLAMRG will create a permutation list which will merge the elements of A (which is composed of two independently sorted sets) into a single set which is sorted in ascending order. That's the whole assignment, bestie 🫶

🧮 Parameters 🧮

  • N1 — N1 is INTEGER.
  • N2 — N2 is INTEGER. These arguments contain the respective lengths of the two sorted lists to be merged.
  • A — A is DOUBLE PRECISION array, dimension (N1+N2). The first N1 elements of A contain a list of numbers which are sorted in either ascending or descending order. Likewise for the final N2 elements.
  • DTRD1 — DTRD1 is INTEGER.
  • DTRD2 — DTRD2 is INTEGER. These are the strides to be taken through the array A. Allowable strides are 1 and -1. They indicate whether a subset of A is sorted in ascending (DTRDx = 1) or descending (DTRDx = -1) order. Only 1 and -1, okay?
  • INDEX — INDEX is INTEGER array, dimension (N1+N2). On exit this array will contain a permutation such that if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be sorted in ascending order. the glow-up is real 🌈
