SRC/zsytrs.f(3)

okay bestie, welcome to the Library Functions Manual page for SRC/zsytrs.f(3) — yes, the .f(3) and all, and it’s giving linear-algebra main character energy 💅✨

💖 NAME 💖

SRC/zsytrs.f

🦋 SYNOPSIS 🦋

✨ Functions/Subroutines ✨

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

🌸 Function/Subroutine Documentation 🌸

   subroutine zsytrs (character uplo, integer n, integer nrhs, complex*16,
       dimension( lda, * ) a, integer lda, integer, dimension( * ) ipiv,
       complex*16, dimension( ldb, * ) b, integer ldb, integer info)
       ZSYTRS

🎯 Purpose 🎯

ZSYTRS 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 ZSYTRF. math slay 🧮✨

🌈 Parameters 🌈

• UPLO — UPLO is CHARACTER*1. 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*16 array, dimension (LDA,N). The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by ZSYTRF. 💜
• 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 ZSYTRF. 🔥
• B — B is COMPLEX*16 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. 🚨
