DGLMTS(3)

💅 DGLMTS(3) 💅

okay so this page lives in the Library Functions Manual, and it's fully about DGLMTS. no cap, it's giving very specific LAPACK test-routine energy and we're here for it. 🦋

🌸 NAME 🌸

The name is literally this path, bestie:

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

✨ SYNOPSIS ✨

🫶 Functions/Subroutines 🫶

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

DGLMTS — that's the whole mood.

DGLMTS

🎀 Purpose 🎀

DGLMTS tests DGGGLM — a subroutine for solving the generalized linear model problem. that's the vibe 💖

💖 Parameters 💖

• N — N is INTEGER; the number of rows of the matrices A and B. N >= 0.
• M — M is INTEGER; the number of columns of the matrix A. M >= 0.
• P — P is INTEGER; the number of columns of the matrix B. P >= 0.
• A — A is DOUBLE PRECISION array, dimension (LDA,M); the N-by-M matrix A.
• AF — AF is DOUBLE PRECISION array, dimension (LDA,M).
• LDA — LDA is INTEGER; the leading dimension of the arrays A, AF. LDA >= max(M,N).
• B — B is DOUBLE PRECISION array, dimension (LDB,P); the source literally says "The N-by-P matrix A." here, so I'm keeping that exactly as written 🫶.
• BF — BF is DOUBLE PRECISION array, dimension (LDB,P).
• LDB — LDB is INTEGER; the leading dimension of the arrays B, BF. LDB >= max(P,N).
• D — D is DOUBLE PRECISION array, dimension( N ); on input, the left hand side of the GLM.
• DF — DF is DOUBLE PRECISION array, dimension( N ).
• X — X is DOUBLE PRECISION array, dimension( M ); solution vector X in the GLM problem.
• U — U is DOUBLE PRECISION array, dimension( P ); solution vector U in the GLM 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; the test ratio:

                           norm( d - A*x - B*u )
            RESULT = -----------------------------------------
                     (norm(A)+norm(B))*(norm(x)+norm(u))*EPS

that's the page, bestie 💖 cute little sign-off for the footer energy: source/version is LAPACK — Version 3.12.0 — and the page path is /home/abui...IG/dglmts.f(3) ✨🎀
