🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/ssytrs_aa.f is the file this page is serving, bestie — it's from the Library Functions Manual, and it's giving “subroutine SSYTRS_AA has entered the chat.” ✨

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines

• subroutine SSYTRS_AA (uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork, info) — the quick little call list, no cap.

   subroutine SSYTRS_AA (uplo, n, nrhs, a, lda, ipiv, b, ldb, work, lwork,
       info)

• SSYTRS_AA — and here's the full signature, coming right up:

   subroutine SSYTRS_AA (character uplo, integer n, integer nrhs, real,
       dimension( lda, * ) a, integer lda, integer, dimension( * ) ipiv, real,
       dimension( ldb, * ) b, integer ldb, real, dimension( * ) work, integer
       lwork, integer info)

🎀 subroutine SSYTRS_AA

   subroutine SSYTRS_AA (character uplo, integer n, integer nrhs, real,
       dimension( lda, * ) a, integer lda, integer, dimension( * ) ipiv, real,
       dimension( ldb, * ) b, integer ldb, real, dimension( * ) work, integer
       lwork, integer info)

✨ Purpose

Okay so SSYTRS_AA solves a system of linear equations A*X = B with a real symmetric matrix A using the factorization A = U**T*T*U or A = L*T*L**T computed by SSYTRF_AA. That's the whole plot, bestie. 💖

🍓 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**T*T*U; = 'L': Lower triangular, form is A = L*T*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 REAL array, dimension (LDA,N). Details of factors computed by SSYTRF_AA.
• 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 as computed by SSYTRF_AA.
• B — B is REAL 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).
• WORK — WORK is REAL array, dimension (MAX(1,LWORK)).
• LWORK — LWORK is INTEGER. The dimension of the array WORK. LWORK >= max(1,3*N-2).
• INFO — INFO is INTEGER. = 0: successful exit. < 0: if INFO = -i, the i-th argument had an illegal value.
