November 2006 Purpose ======= CCHKTZ tests CTZRQF and CTZRZF. 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. 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. A (workspace) COMPLEX 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 (workspace) COMPLEX array, dimension (MMAX*NMAX) S (workspace) REAL array, dimension (min(MMAX,NMAX)) COPYS (workspace) REAL array, dimension (min(MMAX,NMAX)) TAU (workspace) COMPLEX array, dimension (MMAX) WORK (workspace) COMPLEX array, dimension (MMAX*NMAX + 4*NMAX + MMAX) RWORK (workspace) REAL array, dimension (2*NMAX) NOUT (input) INTEGER The unit number for output. ===================================================================== Parameter adjustments */ --rwork; --work; --tau; --copys; --s; --copya; --a; --nval; --mval; --dotype; /* Function Body Initialize constants and the random number seed. */ s_copy(path, "Complex precision", (ftnlen)1, (ftnlen)17); s_copy(path + 1, "TZ", (ftnlen)2, (ftnlen)2); nrun = 0; nfail = 0; nerrs = 0; for (i__ = 1; i__ <= 4; ++i__) { iseed[i__ - 1] = iseedy[i__ - 1]; /* L10: */ } eps = slamch_("Epsilon"); /* Test the error exits */ if (*tsterr) { cerrtz_(path, nout); } infoc_1.infot = 0; i__1 = *nm; for (im = 1; im <= i__1; ++im) { /* Do for each value of M in MVAL. */ m = mval[im]; lda = max(1,m); i__2 = *nn; for (in = 1; in <= i__2; ++in) { /* Do for each value of N in NVAL for which M .LE.
