ZLASET(3)

🌸 NAME 🌸

Bestie, hi, welcome to the ZLASET(3) page from the Library Functions Manual ✨. The NAME section is just the source-file path, and it is exactly this:

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

That's the whole NAME moment. Iconic. 💅

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

• subroutine ZLASET (uplo, m, n, alpha, beta, a, lda) — ZLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values. No cap, that's the summary. 🫶

💖 Function/Subroutine Documentation 💖

The full signature is giving main-character energy, and it is verbatim:

subroutine ZLASET (character uplo, integer m, integer n, complex*16 alpha,
    complex*16 beta, complex*16, dimension( lda, * ) a, integer lda)

And the vibe check is still: ZLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values. Periodt. ✨

🦋 Purpose: 🦋

Here's the source comment block, kept exact because it's code-comment code, iykyk:

!>
!> ZLASET initializes a 2-D array A to BETA on the diagonal and
!> ALPHA on the offdiagonals.
!>

Group-chat translation: diagonal elements go to BETA, off-diagonal elements go to ALPHA. That's the tea. 🍓

🎀 Parameters 🎀

• UPLO — UPLO is CHARACTER*1. It specifies the part of the matrix A to be set. = 'U': the upper triangular part is set, and the lower triangle is unchanged. = 'L': the lower triangular part is set, and the upper triangle is unchanged. Otherwise: All of the matrix A is set. 💖
• M — M is INTEGER. On entry, M specifies the number of rows of A.
• N — N is INTEGER. On entry, N specifies the number of columns of A.
• ALPHA — ALPHA is COMPLEX*16. All the offdiagonal array elements are set to ALPHA.
• BETA — BETA is COMPLEX*16. All the diagonal array elements are set to BETA.
• A — A is COMPLEX*16 array, dimension (LDA,N). On entry, the m by n matrix A. On exit:

A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n, i.ne.j;
A(i,i) = BETA , 1 <= i <= min(m,n)

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

Cute sign-off: the footer says LAPACK Version 3.12.0 and the source path is /home/abui...RC/zlaset.f(3) — no date printed on this footer, so that's the version/source tea, bye bestie 💜🦋
