TESTING/LIN/dchkqp3rk.f(3)

💖 NAME 💖

okay so bestie, this is the TESTING/LIN/dchkqp3rk.f(3) page — Library Functions Manual energy — and the name on the tin is TESTING/LIN/dchkqp3rk.f. It's giving “LAPACK test code, but make it a whole manpage,” and honestly? iconic. 🎀

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

subroutine dchkqp3rk (dotype, nm, mval, nn, nval, nns, nsval, nnb,
    nbval, nxval, thresh, a, copya, b, copyb, s, tau, work, iwork, nout)

DCHKQP3RK — that's the subroutine, no cap. 💅

🎯 Purpose 🎯

DCHKQP3RK tests DGEQP3RK. That's the whole purpose, periodt. 🔥

🧚 Parameters 🧚

• DOTYPE — 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. 💖
• 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. 🎀
• NNS — INTEGER. The number of values of NRHS contained in the vector NSVAL. 💅
• NSVAL — INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS. 👑
• 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 — DOUBLE PRECISION. 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 — DOUBLE PRECISION 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 — DOUBLE PRECISION array, dimension (MMAX*NMAX). 🎀
• B — DOUBLE PRECISION array, dimension (MMAX*NSMAX) where MMAX is the maximum value of M in MVAL and NSMAX is the maximum value of NRHS in NSVAL. 🦋
• COPYB — DOUBLE PRECISION array, dimension (MMAX*NSMAX). ✨
• S — DOUBLE PRECISION array, dimension (min(MMAX,NMAX)). 🌸
• TAU — DOUBLE PRECISION array, dimension (MMAX). 💅
• WORK — DOUBLE PRECISION array, dimension (MMAX*NMAX + 4*NMAX + MMAX). 🧚
• IWORK — INTEGER array, dimension (2*NMAX). 👑
• NOUT — INTEGER. The unit number for output. 💖
