ZLATTR(3)

hey bestie, this page is zlattr.f(3) from the Library Functions Manual — the header/footer path situation is /home/abui...IN/zlattr.f(3), and the energy is very “LAPACK test-matrix generator who absolutely ate.” 🧚💅

🌸 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zlattr.f

✨ SYNOPSIS

🎀 Functions/Subroutines

subroutine ZLATTR (imat, uplo, trans, diag, iseed, n, a, lda, b, work,
    rwork, info)
    ZLATTR

🦋 Function/Subroutine Documentation

subroutine ZLATTR (integer imat, character uplo, character trans, character
    diag, integer, dimension( 4 ) iseed, integer n, complex*16, dimension(
    lda, * ) a, integer lda, complex*16, dimension( * ) b, complex*16,
    dimension( * ) work, double precision, dimension( * ) rwork, integer
    info)

ZLATTR — the main character, periodt. 👑

🎀 Purpose

ZLATTR generates a triangular test matrix in 2-dimensional storage. IMAT and UPLO uniquely specify the properties of the test matrix, which is returned in the array A. No cap. ✨

💅 Parameters

• IMAT — IMAT is INTEGER. An integer key describing which matrix to generate for this path. 🔑
• UPLO — UPLO is CHARACTER*1. Specifies whether the matrix A will be upper or lower triangular.
  • = 'U': Upper triangular
  • = 'L': Lower triangular
• TRANS — TRANS is CHARACTER*1. Specifies whether the matrix or its transpose will be used.
  • = 'N': No transpose
  • = 'T': Transpose
  • = 'C': Conjugate transpose
• DIAG — DIAG is CHARACTER*1. Specifies whether or not the matrix A is unit triangular.
  • = 'N': Non-unit triangular
  • = 'U': Unit triangular
• ISEED — ISEED is INTEGER array, dimension (4). The seed vector for the random number generator (used in ZLATMS). Modified on exit. 🫶
• N — N is INTEGER. The order of the matrix to be generated.
• A — A is COMPLEX*16 array, dimension (LDA,N). The triangular matrix A. If UPLO = 'U', the leading N x N upper triangular part of the array A contains the upper triangular matrix, and the strictly lower triangular part of A is not referenced. If UPLO = 'L', the leading N x N lower triangular part of the array A contains the lower triangular matrix and the strictly upper triangular part of A is not referenced. 🦋
• LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,N). Dimension police are watching, bestie. 👀
• B — B is COMPLEX*16 array, dimension (N). The right hand side vector, if IMAT > 10.
• WORK — WORK is COMPLEX*16 array, dimension (2*N).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (N).
• INFO — INFO is INTEGER.
  • = 0: successful exit
  • < 0: if INFO = -i, the i-th argument had an illegal value

okay bye bestie 💖 this whole page came from LAPACK Version 3.12.0 and the footer path is /home/abui...IN/zlattr.f(3); the footer didn’t print a date, so I’m not inventing one — no cap, just facts. 🎀🌈
