🎀 TESTING/EIG/clsets.f(3) — Library Functions Manual 🎀

okay so bestie, this is the TESTING/EIG/clsets.f page from the Library Functions Manual, and it's basically the test-routine lore for CLSETS 💖 buckle up.

CLSETS

🧚 Function/Subroutine Documentation 🧚

   subroutine clsets (integer m, integer p, integer n, complex, dimension( lda,
       * ) a, complex, dimension( lda, * ) af, integer lda, complex, dimension(
       ldb, * ) b, complex, dimension( ldb, * ) bf, integer ldb, complex,
       dimension( * ) c, complex, dimension( * ) cf, complex, dimension( * ) d,
       complex, dimension( * ) df, complex, dimension( * ) x, complex,

       real, dimension( 2 ) result)

CLSETS

Purpose

CLSETS tests CGGLSE — a subroutine for solving linear equality constrained least square problem (LSE). iykyk 😌

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 COMPLEX array, dimension (LDA,N); the M-by-N matrix A.
• 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).
• B — B is COMPLEX array, dimension (LDB,N); the P-by-N matrix A. yes, the original says A here — we're not fixing it, bestie 😭💀
• 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).
• 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.
• WORK — WORK is COMPLEX 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 are literally:

RESULT(1) = norm( A*x - c )/ norm(A)*norm(X)*EPS
RESULT(2) = norm( B*x - d )/ norm(B)*norm(X)*EPS
