SCHKQP3RK

🎯 Purpose

SCHKQP3RK tests SGEQP3RK. That's the whole purpose, and honestly it ate. 💅

🧾 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the matrix-type selector: type j (for 1 <= j <= NTYPES) is used for testing when DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. No cap.
• NM — NM is INTEGER. It's the number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• NNB — NNB is 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). It's giving matching set energy 🎀
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NXVAL — NXVAL is INTEGER array, dimension (NNB). The values of the crossover point NX.
• 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. That's the "show me everything" setting ✨
• A — A is REAL 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 — COPYA is REAL array, dimension (MMAX*NMAX).
• B — B is REAL 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 — COPYB is REAL array, dimension (MMAX*NSMAX).
• S — S is REAL array, dimension (min(MMAX,NMAX)).
• TAU — TAU is REAL array, dimension (MMAX).
• WORK — WORK is REAL array, dimension (MMAX*NMAX + 4*NMAX + MMAX).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
