🎀 TESTING/EIG/ccklse.f(3) 🎀

okay so this page is from the Library Functions Manual, and it’s giving pure TESTING/EIG/ccklse.f energy. Buckle up, bestie — we’re doing the whole routine, no skipping 💖

🎀 NAME 🎀

TESTING/EIG/ccklse.f — yes bestie, that’s the name, and it’s literally the whole NAME section. slay.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

okay here’s the vibe check:

       subroutine ccklse (nn, mval, pval, nval, nmats, iseed, thresh, nmax, a,
           af, b, bf, x, work, rwork, nin, nout, info)
           CCKLSE

💫 Function/Subroutine Documentation 💫

okay so here’s the full signature, and yes, it’s long. Deep breaths, bestie:

   subroutine ccklse (integer nn, integer, dimension( * ) mval, integer,
       dimension( * ) pval, integer, dimension( * ) nval, integer nmats,
       integer, dimension( 4 ) iseed, real thresh, integer nmax, complex,
       dimension( * ) a, complex, dimension( * ) af, complex, dimension( * ) b,
       complex, dimension( * ) bf, complex, dimension( * ) x, complex,
       dimension( * ) work, real, dimension( * ) rwork, integer nin, integer
       nout, integer info)
       CCKLSE

🌸 Purpose 🌸

CCKLSE tests CGGLSE — a subroutine for solving linear equality constrained least square problem (LSE). That’s the whole purpose, and it absolutely ate 💅

🦋 Parameters 🦋

okay bestie, here’s every single parameter, and I mean every single one:

• NN — INTEGER. The number of values of (M,P,N) contained in the vectors (MVAL, PVAL, NVAL).
• MVAL — INTEGER array, dimension (NN). The values of the matrix row(column) dimension M.
• PVAL — INTEGER array, dimension (NN). The values of the matrix row(column) dimension P.
• NVAL — INTEGER array, dimension (NN). The values of the matrix column(row) dimension N.
• NMATS — INTEGER. The number of matrix types to be tested for each combination of matrix dimensions. If NMATS >= NTYPES (the maximum number of matrix types), then all the different types are generated for testing. If NMATS < NTYPES, another input line is read to get the numbers of the matrix types to be used.
• ISEED — INTEGER array, dimension (4). On entry, the seed of the random number generator. The array elements should be between 0 and 4095, otherwise they will be reduced mod 4096, and ISEED(4) must be odd. On exit, the next seed in the random number sequence after all the test matrices have been generated.
• THRESH — REAL. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0.
• NMAX — INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — COMPLEX array, dimension (NMAX*NMAX).
• AF — COMPLEX array, dimension (NMAX*NMAX).
• B — COMPLEX array, dimension (NMAX*NMAX).
• BF — COMPLEX array, dimension (NMAX*NMAX).
• X — COMPLEX array, dimension (5*NMAX).
• WORK — COMPLEX array, dimension (NMAX*NMAX).
• RWORK — REAL array, dimension (NMAX).
• NIN — INTEGER. The unit number for input.
• NOUT — INTEGER. The unit number for output.
• INFO — INTEGER.
  • = 0 : successful exit
  • > 0 : If CLATMS returns an error code, the absolute value of it is returned.
