CCKLSE(3)

💅 CCKLSE(3) — bestie, it's the LAPACK test driver for CGGLSE

okay so first things first: this page lives in the Library Functions Manual, and the file it's documenting is straight up:

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

(you'll also see it written all cute and truncated as /home/abui...IG/ccklse.f(3) at the top and bottom of the page, that's just the header/footer being dramatic ✨)

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/ccklse.f — yes the "name" is literally the whole path, she's that girl 💅

✨ Purpose ✨

!> !> CCKLSE tests CGGLSE - a subroutine for solving linear equality !> constrained least square problem (LSE). !>

like literally her whole job is vibe-checking CGGLSE 😤 the linear equality constrained least square problem (LSE) solver. no cap.

💖 Parameters 💖

• NN — NN is INTEGER. the number of values of (M,P,N) chillin' inside the vectors (MVAL, PVAL, NVAL). iykyk 🫶
• MVAL — MVAL is INTEGER array, dimension (NN). the values of the matrix row(column) dimension M. 💫
• PVAL — PVAL is INTEGER array, dimension (NN). the values of the matrix row(column) dimension P. 🌸
• NVAL — NVAL is INTEGER array, dimension (NN). the values of the matrix column(row) dimension N. 🦋
• NMATS — NMATS is 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 — she's not picking favourites 💅. If NMATS < NTYPES, another input line is read to get the numbers of the matrix types to be used. 📥
• ISEED — ISEED is 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 (that's a hard requirement, don't test her 🙈). On exit, the next seed in the random number sequence after all the test matrices have been generated. 🎲
• THRESH — THRESH is 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 🔥 (yes, all of them, she will not be stopped).
• NMAX — NMAX is INTEGER. the maximum value permitted for M or N, used in dimensioning the work arrays. 📏
• A — A is COMPLEX array, dimension (NMAX*NMAX). ✨
• AF — AF is COMPLEX array, dimension (NMAX*NMAX). 🦋
• B — B is COMPLEX array, dimension (NMAX*NMAX). 🌸
• BF — BF is COMPLEX array, dimension (NMAX*NMAX). 💜
• X — X is COMPLEX array, dimension (5*NMAX). (five whole NMAXs, she's built different) 🫶
• WORK — WORK is COMPLEX array, dimension (NMAX*NMAX). 🧚
• RWORK — RWORK is REAL array, dimension (NMAX). 🍓
• NIN — NIN is INTEGER. the unit number for input. 📥
• NOUT — NOUT is INTEGER. the unit number for output. 📤
• INFO — INFO is INTEGER. exit status, and the tea is:
  • = 0 : successful exit 🎉 slay
  • > 0 : if CLATMS returns an error code, the absolute value of it is returned 😭 not me getting somebody else's error forwarded straight to me

mmm okay and that's the whole page! 💖

sign-off: this is LAPACK Version 3.12.0, and the footer was out here doing the most with /home/abui...IG/ccklse.f(3) — bye bestie, go run some tests 🎀🦋💅
