✨ NAME ✨

okay bestie, welcome to the csytrs_aa.f(3) page from the Library Functions Manual 💖 this one is literally all about CSYTRS_AA, and the file-name situation is giving full-path main character energy:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/csytrs_aa.f

---

🌸 SYNOPSIS 🌸

Functions/Subroutines — yes, we're in function/subroutine territory, slay ✨

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

and then the name again, because the page said it twice and we do not skip details: CSYTRS_AA.

---

💖 Function/Subroutine Documentation 💖

here's the whole signature, no cap:

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

and yup, CSYTRS_AA again 💅

---

🎯 Purpose 🎯

bestie, here's the actual vibe: CSYTRS_AA solves a system of linear equations A*X = B with a complex symmetric matrix A using the factorization A = U**T*T*U or A = L*T*L**T computed by CSYTRF_AA. iconic linear algebra behavior fr fr 🧚

🌷 Parameters 🌷

• UPLO — the "which triangle are we in" queen 👑 it's CHARACTER*1, and 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 — INTEGER, the order of the matrix A. condition check: N >= 0 ✨
• NRHS — INTEGER, the number of right hand sides, i.e., the number of columns of the matrix B. condition check: NRHS >= 0 🎀
• A — COMPLEX array, dimension (LDA,N). Details of factors computed by CSYTRF_AA.
• LDA — INTEGER, the leading dimension of the array A. condition check: LDA >= max(1,N) 🌸
• IPIV — INTEGER array, dimension (N). Details of the interchanges as computed by CSYTRF_AA.
• B — COMPLEX array, dimension (LDB,NRHS). On entry, the right hand side matrix B. On exit, the solution matrix X. glow-up moment 💫
• LDB — INTEGER, the leading dimension of the array B. condition check: LDB >= max(1,N) 🦋
• WORK — COMPLEX array, dimension (MAX(1,LWORK)).
• LWORK — INTEGER, the dimension of the array WORK. condition check: LWORK >= max(1,3*N-2) 🔥
• INFO — INTEGER:
  • = 0: successful exit
  • < 0: if INFO = -i, the i-th argument had an illegal value
