SRC/zpotrs.f(3)

💖 SRC/zpotrs.f — LAPACK Library Functions Manual 💖

okay so bestie, welcome to the SRC/zpotrs.f(3) page — it's giving LAPACK Library Functions Manual, and today's main character is literally SRC/zpotrs.f. 💅

🦋 NAME 🦋

SRC/zpotrs.f

✨ SYNOPSIS ✨

🧩 Functions/Subroutines 🧩

subroutine zpotrs (uplo, n, nrhs, a, lda, b, ldb, info)
    ZPOTRS

🌸 Function/Subroutine Documentation 🌸

   subroutine zpotrs (character uplo, integer n, integer nrhs, complex*16,
       dimension( lda, * ) a, integer lda, complex*16, dimension( ldb, * ) b,
       integer ldb, integer info)
       ZPOTRS

💜 Purpose 💜

Bestie, ZPOTRS solves a system of linear equations A*X = B with a Hermitian positive definite matrix A using the Cholesky factorization A = U**H * U or A = L * L**H computed by ZPOTRF. That's the whole flex. ✨

🎀 Parameters 🎀

• UPLO — UPLO is CHARACTER*1
  • = 'U': Upper triangle of A is stored;
  • = 'L': Lower triangle of A is stored.
• 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 triangular factor U or L from the Cholesky factorization A = U**H * U or A = L * L**H, as computed by ZPOTRF.
• LDA — LDA is INTEGER — the leading dimension of the array A. LDA >= max(1,N).
• 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
