💖 TESTING/EIG/sglmts.f(3) 💖

Bestie, this page is from the Library Functions Manual, and it's all about TESTING/EIG/sglmts.f — yes, the test routine is serving main character energy. 🧚✨

🌸 NAME 🌸

TESTING/EIG/sglmts.f — that's the name, that's the whole name, and honestly? Iconic. 💅

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

Here's the cast list, no cap:

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

🦋 Function/Subroutine Documentation 🦋

🌟 subroutine sglmts 🌟

Full signature, copied exactly because we do not play with code:

       subroutine sglmts (integer n, integer m, integer p, real, dimension( lda, *
       ) a, real, dimension( lda, * ) af, integer lda, real, dimension( ldb, *
       ) b, real, dimension( ldb, * ) bf, integer ldb, real, dimension( * ) d,
       real, dimension( * ) df, real, dimension( * ) x, real, dimension( * ) u,
       real, dimension( lwork ) work, integer lwork, real, dimension( * )
       rwork, real result)
       SGLMTS

💜 Purpose 💜

SGLMTS tests SGGGLM — a subroutine for solving the generalized linear model problem. Lowkey important, highkey slaying. 🔥

🍓 Parameters 🍓

• N — N is INTEGER. N >= 0. The number of rows of the matrices A and B.
• M — M is INTEGER. M >= 0. The number of columns of the matrix A.
• P — P is INTEGER. P >= 0. The number of columns of the matrix B.
• A — A is REAL array, dimension (LDA,M). The N-by-M matrix A.
• AF — AF is REAL array, dimension (LDA,M). No extra lore, just the type and dimension.
• LDA — LDA is INTEGER. The leading dimension of the arrays A, AF. LDA >= max(M,N).
• B — B is REAL array, dimension (LDB,P). The N-by-P matrix A. (Yes, the page literally says A there — I'm not changing a single character, bestie. 🙈)
• BF — BF is REAL array, dimension (LDB,P). Just the type and dimension, periodt.
• LDB — LDB is INTEGER. The leading dimension of the arrays B, BF. LDB >= max(P,N).
• D — D is REAL array, dimension( N ). On input, the left hand side of the GLM.
• DF — DF is REAL array, dimension( N ). That's the whole note.
• X — X is REAL array, dimension( M ). Solution vector X in the GLM problem.
• U — U is REAL array, dimension( P ). Solution vector U in the GLM problem.
• WORK — WORK is REAL array, dimension (LWORK). That's it, that's the vibe.
• LWORK — LWORK is INTEGER. The dimension of the array WORK.
• RWORK — RWORK is REAL array, dimension (M). Short and sweet.
• RESULT — RESULT is REAL. The test ratio:

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