SCKLSE(3)

Welcome to the SCKLSE(3) page from the Library Functions Manual, bestie! 💖 This page is literally the SCKLSE subroutine documentation, and it is highkey all about testing SGGLSE — a subroutine for solving linear equality constrained least square problem (LSE). No cap, ngl, every parameter and dimension is down below. ✨

🌸 NAME 🌸

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

Yes, the NAME line is a whole path, and it ate. Periodt. 💅

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

Here's the signature exactly as it appears, no edits — I'm obsessed. 🫶

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

💅 Function/Subroutine Documentation 💅

🦋 subroutine SCKLSE 🦋

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

That's the full signature, and the routine's name is SCKLSE — main character energy. 👑

🍓 Parameters 🍓

Every single parameter, bestie — I did not skip a 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 — REAL array, dimension (NMAX*NMAX).
• AF — REAL array, dimension (NMAX*NMAX).
• B — REAL array, dimension (NMAX*NMAX).
• BF — REAL array, dimension (NMAX*NMAX).
• X — REAL array, dimension (5*NMAX).
• WORK — REAL 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 SLATMS returns an error code, the absolute value of it is returned.
