CLASWP(3)

📦 version 3.12.0, in opensuse-leap 16.0

🌸 NAME 🌸

Hey bestie 💖 welcome to CLASWP(3), a Library Functions Manual page, and the file it’s serving is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/claswp.f. The page header path is /home/abui...RC/claswp.f(3). Yes, the whole path is the name section, slay.

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

  • subroutine CLASWP (n, a, lda, k1, k2, ipiv, incx) — does a whole series of row interchanges on a general rectangular matrix.

🦋 Function/Subroutine Documentation 🦋

💅 subroutine CLASWP (...).

subroutine CLASWP (integer n, complex, dimension( lda, * ) a, integer lda, integer k1, integer k2, integer, dimension( * ) ipiv, integer incx)

Okay so CLASWP is the row-interchange bestie for a general rectangular matrix. No cap.

💖 Purpose 💖

CLASWP performs a series of row interchanges on the matrix A. One row interchange gets initiated for each of rows K1 through K2 of A. That’s the whole vibe. 🫶

🌈 Parameters 🌈

  • N — N is INTEGER. The number of columns of the matrix A.
  • A — A is COMPLEX array, dimension (LDA,N). On entry, the matrix of column dimension N to which the row interchanges will be applied. On exit, the permuted matrix.
  • LDA — LDA is INTEGER. The leading dimension of the array A.
  • K1 — K1 is INTEGER. The first element of IPIV for which a row interchange will be done.
  • K2 — K2 is INTEGER. (K2-K1+1) is the number of elements of IPIV for which a row interchange will be done.
  • IPIV — IPIV is INTEGER array, dimension (K1+(K2-K1)*abs(INCX)). The vector of pivot indices. Only the elements in positions K1 through K1+(K2-K1)*abs(INCX) of IPIV are accessed. IPIV(K1+(K-K1)*abs(INCX)) = L implies rows K and L are to be interchanged.
  • INCX — INCX is INTEGER. The increment between successive values of IPIV. If INCX is negative, the pivots are applied in reverse order.

That’s the tea, bestie! This page is LAPACK Version 3.12.0, footer path /home/abui...RC/claswp.f(3), and the footer doesn’t give a date, so I’m not inventing one 🫶💅✨
