DLSETS(3)

🦋 dlsets.f(3) — Library Functions Manual 🦋

okay so bestie, this is the dlsets.f(3) page from the Library Functions Manual, and it is literally all about the DLSETS subroutine. Buckle up, we're doing Fortran testing lore 💅✨

🌸 NAME 🌸

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

That's the whole name line, no cap. 🎀

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

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

🌈 Function/Subroutine Documentation 🌈

💅 subroutine DLSETS 💅

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

🌟 Purpose 🌟

DLSETS tests DGGLSE - a subroutine for solving linear equality constrained least square problem (LSE). That's the whole purpose, bestie. slay ✨

🍓 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 DOUBLE PRECISION array, dimension (LDA,N). The M-by-N matrix A.
• AF — AF is DOUBLE PRECISION 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 DOUBLE PRECISION array, dimension (LDB,N). The P-by-N matrix A. (yes, it says A right there in the source, bestie — I'm not fixing it 💀)
• BF — BF is DOUBLE PRECISION 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 DOUBLE PRECISION array, dimension( M ). the vector C in the LSE problem.
• CF — CF is DOUBLE PRECISION array, dimension( M ).
• D — D is DOUBLE PRECISION array, dimension( P ). the vector D in the LSE problem.
• DF — DF is DOUBLE PRECISION array, dimension( P ).
• X — X is DOUBLE PRECISION array, dimension( N ). solution vector X in the LSE problem.
• WORK — WORK is DOUBLE PRECISION array, dimension (LWORK).
• LWORK — LWORK is INTEGER. The dimension of the array WORK.
• RWORK — RWORK is DOUBLE PRECISION array, dimension (M).
• RESULT — RESULT is DOUBLE PRECISION 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
