💅 lacp2(3) — Library Functions Manual, bestie 💅

okay so this is lacp2(3) from the Library Functions Manual, and it is literally the “copy a real matrix into a complex matrix” moment. no cap, it's giving “small routine, big main character energy.” 💖

🌸 NAME 🌸

  • lacp2 — lacp2: general matrix, convert real to complex

✨ SYNOPSIS ✨

Functions

subroutine clacp2 (uplo, m, n, a, lda, b, ldb)
subroutine zlacp2 (uplo, m, n, a, lda, b, ldb)
  • clacp2 — CLACP2 copies all or part of a real two-dimensional array to a complex array. 💫
  • zlacp2 — ZLACP2 copies all or part of a real two-dimensional array to a complex array. 💫

🦋 Detailed Description 🦋

okay so the original page has a Detailed Description heading and then… nothing before Function Documentation. minimal. iconic. keeping it for structure. 🫶

💖 Function Documentation 💖

🎀 subroutine clacp2 🎀

subroutine clacp2 (character uplo, integer m, integer n, real, dimension(
       lda, * ) a, integer lda, complex, dimension( ldb, * ) b, integer ldb)

CLACP2 copies all or part of a real two-dimensional array to a complex array.

Purpose: the source comment says !> CLACP2 copies all or part of a real two-dimensional matrix A to a complex matrix B. (yes, with the !> markers doing their little Doxygen thing ✨)

Parameters

  • UPLO — UPLO is CHARACTER*1. Specifies the part of the matrix A to be copied to B: = 'U': upper triangular part; = 'L': lower triangular part; Otherwise: all of the matrix A. 👑
  • M — M is INTEGER. The number of rows of the matrix A. M >= 0.
  • N — N is INTEGER. The number of columns of the matrix A. N >= 0.
  • A — A is REAL array, dimension (LDA,N). The m by n matrix A. If UPLO = 'U', only the upper trapezium is accessed; if UPLO = 'L', only the lower trapezium is accessed. 🦋
  • LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,M).
  • B — B is COMPLEX array, dimension (LDB,N). On exit, B = A in the locations specified by UPLO.
  • LDB — LDB is INTEGER. The leading dimension of the array B. LDB >= max(1,M).

🎀 subroutine zlacp2 🎀

subroutine zlacp2 (character uplo, integer m, integer n, double precision,
       dimension( lda, * ) a, integer lda, complex*16, dimension( ldb, * ) b,
       integer ldb)

ZLACP2 copies all or part of a real two-dimensional array to a complex array.

Purpose: the source comment says !> ZLACP2 copies all or part of a real two-dimensional matrix A to a complex matrix B. (same !> marker energy, same slay ✨)

Parameters

  • UPLO — UPLO is CHARACTER*1. Specifies the part of the matrix A to be copied to B: = 'U': upper triangular part; = 'L': lower triangular part; Otherwise: all of the matrix A. 👑
  • M — M is INTEGER. The number of rows of the matrix A. M >= 0.
  • N — N is INTEGER. The number of columns of the matrix A. N >= 0.
  • A — A is DOUBLE PRECISION array, dimension (LDA,N). The m by n matrix A. If UPLO = 'U', only the upper trapezium is accessed; if UPLO = 'L', only the lower trapezium is accessed. 🦋
  • LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,M).
  • B — B is COMPLEX*16 array, dimension (LDB,N). On exit, B = A in the locations specified by UPLO.
  • LDB — LDB is INTEGER. The leading dimension of the array B. LDB >= max(1,M).
