SLASWP(3)

SLASWP(3) — row-swap era, bestie 💅

okay so this is the Library Functions Manual page for SLASWP(3) ✨. The top-header path is /home/abui...RC/slaswp.f(3) — and yes, that little path appears twice in the header line, iykyk 😭. We’re folding the manual name in here instead of copy-pasting the header line, because we’re doing this with style. 🫶

🌸 NAME 🌸

The NAME section is literally a build path, no cap: /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/slaswp.f 🍓

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

subroutine SLASWP (n, a, lda, k1, k2, ipiv, incx)

SLASWP performs a series of row interchanges on a general rectangular matrix. That’s the whole vibe. 💫

🦋 Function/Subroutine Documentation 🦋

subroutine SLASWP (integer n, real, dimension( lda, * ) a, integer lda,
    integer k1, integer k2, integer, dimension( * ) ipiv, integer incx)

SLASWP performs a series of row interchanges on a general rectangular matrix. Again: iconic, focused, row-swappy. 👑

💖 Purpose 💖

SLASWP performs a series of row interchanges on the matrix A. One row interchange is initiated for each of rows K1 through K2 of A. That’s it, that’s the purpose, periodt 💅

🌈 Parameters 🌈

• N — N is INTEGER. It’s the number of columns of the matrix A. 💐
• A — A is REAL array, dimension (LDA,N). On entry, it’s the matrix of column dimension N to which the row interchanges will be applied. On exit, it’s the permuted matrix. Glow-up complete ✨
• LDA — LDA is INTEGER. It’s the leading dimension of the array A. 🎀
• K1 — K1 is INTEGER. It’s 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. Math but make it cute 🧮💖
• IPIV — IPIV is INTEGER array, dimension (K1+(K2-K1)*abs(INCX)). It’s the vector of pivot indices. Only the elements in positions K1 through K1+(K2-K1)*abs(INCX) of IPIV are accessed. And IPIV(K1+(K-K1)*abs(INCX)) = L implies rows K and L are to be interchanged. Pivot lore, unlocked 🔐
• INCX — INCX is INTEGER. It’s the increment between successive values of IPIV. If INCX is negative, the pivots are applied in reverse order. Reverse order? She contains multitudes 💀✨
