CSYTRS(3)

📦 version 3.12.0, in opensuse-leap 16.0

💖 NAME 💖

CSYTRS(3) — okay bestie, this page is from the Library Functions Manual, and the source file is literally /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/csytrs.f.

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

One subroutine is on the menu:

subroutine CSYTRS (uplo, n, nrhs, a, lda, ipiv, b, ldb, info)
    CSYTRS

It’s giving CSYTRS, no cap.

💅 Function/Subroutine Documentation 💅

🦋 subroutine CSYTRS 🦋

subroutine CSYTRS (character uplo, integer n, integer nrhs, complex,
dimension( lda, * ) a, integer lda, integer, dimension( * ) ipiv,
complex, dimension( ldb, * ) b, integer ldb, integer info)

CSYTRS — that’s the main character, obviously.

🌸 Purpose 🌸

CSYTRS solves a system of linear equations A*X = B with a complex symmetric matrix A using the factorization A = U*D*U**T or A = L*D*L**T computed by CSYTRF.

🍓 Parameters 🍓

  • UPLO — UPLO is CHARACTER*1. It specifies whether the details of the factorization are stored as an upper or lower triangular matrix. = 'U': upper triangular, form is A = U*D*U**T; = 'L': lower triangular, form is A = L*D*L**T.
  • N — N is INTEGER. The order of the matrix A. N >= 0.
  • NRHS — NRHS is INTEGER. The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
  • A — A is COMPLEX array, dimension (LDA,N). The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by CSYTRF.
  • LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,N).
  • IPIV — IPIV is INTEGER array, dimension (N). Details of the interchanges and the block structure of D as determined by CSYTRF.
  • B — B is COMPLEX array, dimension (LDB,NRHS). On entry, the right hand side matrix B. On exit, the solution matrix X.
  • LDB — LDB is INTEGER. The leading dimension of the array B. LDB >= max(1,N).
  • INFO — INFO is INTEGER. = 0: successful exit. < 0: if INFO = -i, the i-th argument had an illegal value.
