SLSETS(3)

📦 version 3.12.0, in opensuse-leap 16.0

SLSETS(3) · Library Functions Manual · slsets.f(3) — okay bestie, this is the LAPACK page for the SLSETS test routine, and we're doing a full vibe check without dropping a single fact. 💖

📛 NAME 📛

The NAME is literally this file path, no cap:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/slsets.f

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

The synopsis says SLSETS is a subroutine with this exact shape:

subroutine SLSETS (m, p, n, a, af, lda, b, bf, ldb, c, cf, d, df, x, work, lwork, rwork, result)
    SLSETS

🧚 Function/Subroutine Documentation 🧚

Here's the full signature, character-for-character, because we do not play games with Fortran declarations:

subroutine SLSETS (integer m, integer p, integer n, real, dimension( lda, * ) a, real, dimension( lda, * ) af, integer lda, real, dimension( ldb, * ) b, real, dimension( ldb, * ) bf, integer ldb, real, dimension( * ) c, real, dimension( * ) cf, real, dimension( * ) d, real, dimension( * ) df, real, dimension( * ) x, real, dimension( lwork ) work, integer lwork, real, dimension( * ) rwork, real, dimension( 2 ) result)
    SLSETS

🎯 Purpose 🎯

!>
!> SLSETS tests SGGLSE - a subroutine for solving linear equality
!> constrained least square problem (LSE).
!>

Translation: it tests SGGLSE, the subroutine for solving linear equality constrained least square problem (LSE). That's the whole purpose, periodt. 👑

🌸 Parameters 🌸

  • M — M is INTEGER. The number of rows of the matrix A. M >= 0. 💖
  • P — P is INTEGER. The number of rows of the matrix B. P >= 0. ✨
  • N — N is INTEGER. The number of columns of the matrices A and B. N >= 0. 🦋
  • A — A is REAL array, dimension (LDA,N). The M-by-N matrix A. 🌸
  • AF — AF is REAL array, dimension (LDA,N). 💅
  • LDA — LDA is INTEGER. The leading dimension of the arrays A, AF, Q and R. LDA >= max(M,N). 🎀
  • B — B is REAL array, dimension (LDB,N). The P-by-N matrix A. (Yes bestie, the source says A there, and we are not fixing it.) 🫶
  • BF — BF is REAL array, dimension (LDB,N). 🌈
  • LDB — LDB is INTEGER. The leading dimension of the arrays B, BF, V and S. LDB >= max(P,N). ⭐
  • C — C is REAL array, dimension( M ). The vector C in the LSE problem. 💜
  • CF — CF is REAL array, dimension( M ). 🍓
  • D — D is REAL array, dimension( P ). The vector D in the LSE problem. 🧚
  • DF — DF is REAL array, dimension( P ). 🙈
  • X — X is REAL array, dimension( N ). Solution vector X in the LSE problem. 🔥
  • WORK — WORK is REAL array, dimension (LWORK). 💀
  • LWORK — LWORK is INTEGER. The dimension of the array WORK. ✨
  • RWORK — RWORK is REAL array, dimension (M). 🌸
  • RESULT — RESULT is REAL array, dimension (2). The test ratios:
RESULT(1) = norm( A*x - c )/ norm(A)*norm(X)*EPS
RESULT(2) = norm( B*x - d )/ norm(B)*norm(X)*EPS
