🎯 Purpose 🎯

Okay so the whole point: SCHKQL tests SGEQLF, SORGQL and SORMQL. That's the purpose, bestie. Periodt. 💅

🌈 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.
• NM — NM is INTEGER. 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.
• 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).
• 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.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• 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.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — A is REAL array, dimension (NMAX*NMAX).
• AF — AF is REAL array, dimension (NMAX*NMAX).
• AQ — AQ is REAL array, dimension (NMAX*NMAX).
• AL — AL is REAL array, dimension (NMAX*NMAX).
• AC — AC is REAL array, dimension (NMAX*NMAX).
• B — B is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• TAU — TAU is REAL array, dimension (NMAX).
• WORK — WORK is REAL array, dimension (NMAX*NMAX).
• RWORK — RWORK is REAL array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.

💖 That's the page, bestie. Source/version sign-off: LAPACK Version 3.12.0, page path /home/abui...IN/schkql.f(3). The date isn't printed here, so I'm not inventing one — just keeping the facts cute and correct. Stay sliving. 💅✨
