ZSPTRS(3)

💖 NAME 💖

bestie, this is the zsptrs.f(3) page from the Library Functions Manual ✨ and the file it documents lives at:

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

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

• subroutine ZSPTRS (uplo, n, nrhs, ap, ipiv, b, ldb, info) — the routine itself, no cap.
• ZSPTRS — yes, that's the name, main character energy.

🫶 Function/Subroutine Documentation 🫶

   subroutine ZSPTRS (character uplo, integer n, integer nrhs, complex*16,
       dimension( * ) ap, integer, dimension( * ) ipiv, complex*16, dimension(
       ldb, * ) b, integer ldb, integer info)

ZSPTRS — that's the name of this icon 👑.

🌸 Purpose 🌸

okay so ZSPTRS solves a system of linear equations A*X = B with a complex symmetric matrix A stored in packed format using the factorization A = U*D*U**T or A = L*D*L**T computed by ZSPTRF. literally that's the whole vibe 🔥.

🍓 Parameters 🍓

• UPLO — CHARACTER*1. Specifies whether the details of the factorization are stored as an upper or lower triangular matrix. The tea:
  • = 'U': Upper triangular, form is A = U*D*U**T;
  • = 'L': Lower triangular, form is A = L*D*L**T.
• N — INTEGER. The order of the matrix A. N >= 0.
• NRHS — INTEGER. The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
• AP — COMPLEX*16 array, dimension (N*(N+1)/2). The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by ZSPTRF, stored as a packed triangular matrix.
• IPIV — INTEGER array, dimension (N). Details of the interchanges and the block structure of D as determined by ZSPTRF.
• B — COMPLEX*16 array, dimension (LDB,NRHS). On entry, the right hand side matrix B. On exit, the solution matrix X.
• LDB — INTEGER. The leading dimension of the array B. LDB >= max(1,N).
• INFO — INTEGER.
  • = 0: successful exit
  • < 0: if INFO = -i, the i-th argument had an illegal value
