ILASLC(3)

✨ ILASLC ✨

okay so real talk, this page lives in the Library Functions Manual section (that's the manpage fam it rolls with), and the actual file it's documenting is:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/ilaslc.f

like that's the whole NAME situation, no cap. she's a Fortran file, she's iconic, let's go 💅

🌸 SYNOPSIS 🌸

Functions/Subroutines

• integer function ILASLC (m, n, a, lda) — ILASLC scans a matrix for its last non-zero column. that's it. that's the job. 🎀

🦋 Function/Subroutine Documentation 🦋

integer function ILASLC (integer m, integer n, real, dimension( lda, * ) a,
    integer lda)

ILASLC scans a matrix for its last non-zero column. literally her entire personality 🫶

💖 Purpose:

!>
!> ILASLC scans A for its last non-zero column.
!>

she walks through A and finds the last column that isn't all zeros. main character energy fr fr ✨

🍓 Parameters

• M

!>          M is INTEGER
!>          The number of rows of the matrix A.
!>

so M is an INTEGER and it's how many rows A has. the height. the vertical vibe check 📏

• N

!>          N is INTEGER
!>          The number of columns of the matrix A.
!>

N is an INTEGER too, and it's the number of columns of A — the width, the horizontal situation, the "how many columns am I scanning bestie" number 🌈

• A

!>          A is REAL array, dimension (LDA,N)
!>          The m by n matrix A.
!>

A is a REAL array with dimension (LDA,N), and it's the m by n matrix A. yes she's the star of the show, the whole reason we're here 👑

• LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A. LDA >= max(1,M).
!>

LDA is an INTEGER, it's the leading dimension of the array A, and the rule is LDA >= max(1,M). like respect the constraint or she will simply not behave 💀

💌 cute little sign-off: this gorgeousness comes from LAPACK, Version 3.12.0 — and the footer line wraps up with that same truncated source path /home/abui...RC/ilaslc.f(3) where the date slot usually sits. mwah, go scan some matrices 💅🎀
