TESTING/LIN/cchkq3.f(3)

🌸 NAME 🌸

TESTING/LIN/cchkq3.f — okay bestie, this is the manual page for the cchkq3 routine, and the manual name is TESTING/LIN/cchkq3.f(3) from the Library Functions Manual. It lives in LAPACK’s TESTING/LIN corner, and it’s giving very specific numerical-testing energy. 💖

🦋 Purpose 🦋

!>
!> CCHKQ3 tests CGEQP3.

So yeah, the whole purpose is literally: CCHKQ3 tests CGEQP3. That’s the tea. 🫖✨

🌈 Parameters 🌈

• DOTYPE — LOGICAL array, dimension (NTYPES). These are 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. 💅
• NM — INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix column dimension N.
• NNB — INTEGER. The number of values of NB and NX contained in the vectors NBVAL and NXVAL. The blocking parameters are used in pairs (NB,NX). ✨
• NBVAL — INTEGER array, dimension (NNB). The values of the blocksize NB.
• NXVAL — INTEGER array, dimension (NNB). The values of the crossover point NX.
• 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. 👑
• A — COMPLEX array, dimension (MMAX*NMAX) where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL.
• COPYA — COMPLEX array, dimension (MMAX*NMAX).
• S — REAL array, dimension (min(MMAX,NMAX)).
• TAU — COMPLEX array, dimension (MMAX).
• WORK — COMPLEX array, dimension (max(M*max(M,N) + 4*min(M,N) + max(M,N))).
• RWORK — REAL array, dimension (4*NMAX).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output.

Okay bestie, cute little sign-off time: the source/version from the footer is LAPACK, Version 3.12.0, and the manual page is TESTING/LIN/cchkq3.f(3). There’s no date in that footer, so no fake date tea from me. 💖✨🎀
