CDRVPP(3)

okay bestie, welcome to cdrvpp.f(3) from the Library Functions Manual — yes, the header path is /home/abui...IN/cdrvpp.f(3), and we're about to get into the whole CDRVPP situation. Buckle up, it's giving LAPACK testing subroutine realness 💅✨

🌟 NAME 🌟

This page is for:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cdrvpp.f

That's it. That's the name. The path ate and left no crumbs. 💖

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines 🧚

subroutine CDRVPP (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, asav, b, bsav, x, xact, s, work, rwork, nout)

And yep — CDRVPP. The name is CDRVPP. We love a consistent icon. 👑

✨ Function/Subroutine Documentation ✨

Here's the full signature, exactly as the page serves it:

subroutine CDRVPP (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex, dimension( * ) asav, complex, dimension( * ) b, complex, dimension( * ) bsav, complex, dimension( * ) x, complex, dimension( * ) xact, real, dimension( * ) s, complex, dimension( * ) work, real, dimension( * ) rwork, integer nout)

CDRVPP again, because the documentation wanted an encore. 💅

🎀 Purpose: 🎀

CDRVPP tests the driver routines CPPSV and -SVX. That's the whole purpose, and it's lowkey iconic. (The source wraps this in !> Doxygen markers, if you were wondering about the lil' comment-core vibe.) 🔥

🌸 Parameters 🌸

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used for testing: matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. No cap, that's the whole rule. 💅
• NN — NN is INTEGER. It's literally the number of values of N contained in the vector NVAL. Count 'em, bestie. ✨
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N. Slay. 🌸
• NRHS — NRHS is INTEGER. It's the number of right hand side vectors to be generated for each linear system. Fr fr. 🫶
• THRESH — THRESH is REAL. It's 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. Periodt. 🔥
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. Cute. 🎀
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. Big main character energy for the array sizes. 👑
• A — A is COMPLEX array, dimension (NMAX*(NMAX+1)/2). That's the dimension, and it's serving exactly that. 💜
• AFAC — AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2). Same energy, different array. ✨
• ASAV — ASAV is COMPLEX array, dimension (NMAX*(NMAX+1)/2). The save-file of the group chat, dimension-wise. 🎀
• B — B is COMPLEX array, dimension (NMAX*NRHS). That's the dimension, bestie. No notes. 💖
• BSAV — BSAV is COMPLEX array, dimension (NMAX*NRHS). Backup B behavior, but make it documentation. 🦋
• X — X is COMPLEX array, dimension (NMAX*NRHS). Dimension check: yes. ✅
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS). Exactly that. 💅
• S — S is REAL array, dimension (NMAX). Short, real, and to the point. 🌈
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NRHS)). The max(3,NRHS) is doing its little thing, and we respect it. 🫶
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS). That's the dimension, and that's the vibe. ⭐
• NOUT — NOUT is INTEGER. It's the unit number for output. Put it on the board. 👑
