November 2006 Purpose ======= SCHKQL tests SGEQLF, SORGQL and SORMQL. Arguments ========= DOTYPE (input) 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 (input) INTEGER The number of values of M contained in the vector MVAL. MVAL (input) INTEGER array, dimension (NM) The values of the matrix row dimension M. NN (input) INTEGER The number of values of N contained in the vector NVAL. NVAL (input) INTEGER array, dimension (NN) The values of the matrix column dimension N. NNB (input) 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 (input) INTEGER array, dimension (NNB) The values of the blocksize NB. NXVAL (input) INTEGER array, dimension (NNB) The values of the crossover point NX. NRHS (input) INTEGER The number of right hand side vectors to be generated for each linear system. THRESH (input) 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 (input) LOGICAL Flag that indicates whether error exits are to be tested. NMAX (input) INTEGER The maximum value permitted for M or N, used in dimensioning the work arrays. A (workspace) REAL array, dimension (NMAX*NMAX) AF (workspace) REAL array, dimension (NMAX*NMAX) AQ (workspace) REAL array, dimension (NMAX*NMAX) AL (workspace) REAL array, dimension (NMAX*NMAX) AC (workspace) REAL array, dimension (NMAX*NMAX) B (workspace) REAL array, dimension (NMAX*NRHS) X (workspace) REAL array, dimension (NMAX*NRHS) XACT (workspace) REAL array, dimension (NMAX*NRHS) TAU (workspace) REAL array, dimension (NMAX) WORK (workspace) REAL array, dimension (NMAX*NMAX) RWORK (workspace) REAL array, dimension (NMAX) IWORK (workspace) INTEGER array, dimension (NMAX) NOUT (input) INTEGER The unit number for output. ===================================================================== Parameter adjustments */ --iwork; --rwork; --work; --tau; --xact; --x; --b; --ac; --al; --aq; --af; --a; --nxval; --nbval; --nval; --mval; --dotype; /* Function Body Initialize constants and the random number seed. */ s_copy(path, "Single precision", (ftnlen)1, (ftnlen)16); s_copy(path + 1, "QL", (ftnlen)2, (ftnlen)2); nrun = 0; nfail = 0; nerrs = 0; for (i__ = 1; i__ <= 4; ++i__) { iseed[i__ - 1] = iseedy[i__ - 1]; /* L10: */ } /* Test the error exits */ if (*tsterr) { serrql_(path, nout); } infoc_1.infot = 0; xlaenv_(&c__2, &c__2); lda = *nmax; lwork = *nmax * max(*nmax,*nrhs); /* Do for each value of M in MVAL. */ i__1 = *nm; for (im = 1; im <= i__1; ++im) { m = mval[im]; /* Do for each value of N in NVAL. */ i__2 = *nn; for (in = 1; in <= i__2; ++in) { n = nval[in]; minmn = min(m,n); for (imat = 1; imat <= 8; ++imat) { /* Do the tests only if DOTYPE( IMAT ) is true. */ if (!
