CCHKRQ(3)

CCHKRQ(3) 🌈 Library Functions Manual

Okay bestie, welcome to the CCHKRQ(3) manual page. It's giving Fortran test-driver realness, and honestly? Iconic.

NAME ✨

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

That's the file path for CCHKRQ, and we're obsessed. 💅

Purpose 🎯

CCHKRQ tests CGERQF, CUNGRQ and CUNMRQ. That's the assignment, bestie. No cap.

Parameters 📋

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). This is the matrix-type guest list: 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 COMPLEX array, dimension (NMAX*NMAX).
• AF — AF is COMPLEX array, dimension (NMAX*NMAX).
• AQ — AQ is COMPLEX array, dimension (NMAX*NMAX).
• AR — AR is COMPLEX array, dimension (NMAX*NMAX).
• AC — AC is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NRHS).
• X — X is COMPLEX array, dimension (NMAX*NRHS).
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS).
• TAU — TAU is COMPLEX array, dimension (NMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*NMAX).
• RWORK — RWORK is REAL array, dimension (NMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER: the unit number for output.
