🌸 SLAUU2(3) — Library Functions Manual 🌸

okay so bestie, this is the manual page for /home/abui...RC/slauu2.f(3) — and the manual name is Library Functions Manual, so you know exactly what vibe you're in 💅. We're talking about the SLAUU2 routine, and yes it's giving unblocked algorithm energy ✨.

That's the file, periodt. 🎀

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines 🧚

       subroutine SLAUU2 (uplo, n, a, lda, info)

SLAUU2 computes the product UUH or LHL, where U and L are upper or lower triangular matrices (unblocked algorithm). Slay. 💅

🫶 Function/Subroutine Documentation 🫶

   subroutine SLAUU2 (character uplo, integer n, real, dimension( lda, * ) a,
       integer lda, integer info)

SLAUU2 computes the product UUH or LHL, where U and L are upper or lower triangular matrices (unblocked algorithm). Yes, we said it twice — the manual said it twice too, bestie 😌.

✨ Purpose ✨

So here's the tea: SLAUU2 computes the product U * U**T or L**T * L, where the triangular factor U or L is stored in the upper or lower triangular part of the array A. 🫶

If UPLO = 'U' or 'u', then the upper triangle of the result is stored, overwriting the factor U in A. If UPLO = 'L' or 'l', then the lower triangle of the result is stored, overwriting the factor L in A. Literally iconic. 💅

This is the unblocked form of the algorithm, calling Level 2 BLAS. No cap. ✨

🎀 Parameters 🎀

• UPLO — UPLO is CHARACTER*1. Specifies whether the triangular factor stored in the array A is upper or lower triangular:
  • = 'U': Upper triangular
  • = 'L': Lower triangular
• N — N is INTEGER. The order of the triangular factor U or L. N >= 0.
• A — A is REAL array, dimension (LDA,N). On entry, the triangular factor U or L. On exit, if UPLO = 'U', the upper triangle of A is overwritten with the upper triangle of the product U * U**T; if UPLO = 'L', the lower triangle of A is overwritten with the lower triangle of the product L**T * L.
• LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,N).
• INFO — INFO is INTEGER.
  • = 0: successful exit
  • < 0: if INFO = -k, the k-th argument had an illegal value

okay bestie, cute sign-off time: the footer says LAPACK Version 3.12.0 and /home/abui...RC/slauu2.f(3) — that's the source/version and page-path vibe, fr fr. 💜🦋
