CLSETS(3)

okay bestie, welcome to CLSETS(3) from the Library Functions Manual — this is the group chat where linear equality constrained least squares gets solved, and yes, it's giving main character energy 💅✨

CLSETS

🎯 Purpose

okay so the whole vibe is this: CLSETS tests CGGLSE — a subroutine for solving linear equality constrained least square problem (LSE). periodt. 💖

📋 Parameters

• M — M is INTEGER. The number of rows of the matrix A. M >= 0. no cap.
• P — P is INTEGER. The number of rows of the matrix B. P >= 0. slay.
• N — N is INTEGER. The number of columns of the matrices A and B. N >= 0. iconic.
• A — A is COMPLEX array, dimension (LDA,N). The M-by-N matrix A. literally.
• AF — AF is COMPLEX array, dimension (LDA,N). 🦋
• LDA — LDA is INTEGER. The leading dimension of the arrays A, AF, Q and R. LDA >= max(M,N). keep that constraint, bestie.
• B — B is COMPLEX array, dimension (LDB,N). The P-by-N matrix A. yes, the page says A here — I'm not fixing the lore 💀
• BF — BF is COMPLEX array, dimension (LDB,N). 🫶
• LDB — LDB is INTEGER. The leading dimension of the arrays B, BF, V and S. LDB >= max(P,N). highkey important.
• C — C is COMPLEX array, dimension( M ). the vector C in the LSE problem. 💜
• CF — CF is COMPLEX array, dimension( M ). ✨
• D — D is COMPLEX array, dimension( P ). the vector D in the LSE problem. 🌸
• DF — DF is COMPLEX array, dimension( P ). 🎀
• X — X is COMPLEX array, dimension( N ). solution vector X in the LSE problem. main character vector fr fr.
• WORK — WORK is COMPLEX array, dimension (LWORK). 🌈
• LWORK — LWORK is INTEGER. The dimension of the array WORK. okay werk.
• 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

that's the whole test-ratio moment, no skips 🔥
