CLAUUM(3)

💅 NAME 💅

clauum.f(3) — Library Functions Manual — is the manual name, bestie. The file it documents is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/clauum.f. ✨

🦋 SYNOPSIS 🦋

🌸 Functions/Subroutines 🌸

• subroutine CLAUUM (uplo, n, a, lda, info) — CLAUUM computes the product UUH or LHL, where U and L are upper or lower triangular matrices (blocked algorithm). 💖

🎀 Function/Subroutine Documentation 🎀

subroutine CLAUUM (character uplo, integer n, complex, dimension( lda, * )
       a, integer lda, integer info)

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

🔥 Purpose 🔥

Okay so CLAUUM computes the product U * U**H or L**H * 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. 😭🔥

This is the blocked form of the algorithm, calling Level 3 BLAS. Periodt. 👑

🎀 Parameters 🎀

• UPLO — UPLO is CHARACTER*1. It 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 COMPLEX 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**H; if UPLO = 'L', the lower triangle of A is overwritten with the lower triangle of the product L**H * 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. 💀
