November 2006 Purpose ======= ZCHKEC tests eigen- condition estimation routines ZTRSYL, CTREXC, CTRSNA, CTRSEN In all cases, the routine runs through a fixed set of numerical examples, subjects them to various tests, and compares the test results to a threshold THRESH. In addition, ZTRSNA and CTRSEN are tested by reading in precomputed examples from a file (on input unit NIN). Output is written to output unit NOUT. Arguments ========= THRESH (input) DOUBLE PRECISION Threshold for residual tests. A computed test ratio passes the threshold if it is less than THRESH. TSTERR (input) LOGICAL Flag that indicates whether error exits are to be tested. NIN (input) INTEGER The logical unit number for input. NOUT (input) INTEGER The logical unit number for output. ===================================================================== */ s_copy(path, "Zomplex precision", (ftnlen)1, (ftnlen)17); s_copy(path + 1, "EC", (ftnlen)2, (ftnlen)2); eps = dlamch_("P"); sfmin = dlamch_("S"); io___4.ciunit = *nout; s_wsfe(&io___4); e_wsfe(); io___5.ciunit = *nout; s_wsfe(&io___5); do_fio(&c__1, (char *)&eps, (ftnlen)sizeof(doublereal)); do_fio(&c__1, (char *)&sfmin, (ftnlen)sizeof(doublereal)); e_wsfe(); io___6.ciunit = *nout; s_wsfe(&io___6); do_fio(&c__1, (char *)&(*thresh), (ftnlen)sizeof(doublereal)); e_wsfe(); /* Test error exits if TSTERR is .TRUE. */ if (*tsterr) { zerrec_(path, nout); } ok = TRUE_; zget35_(&rtrsyl, <rsyl, &ntrsyl, &ktrsyl, nin); if (rtrsyl > *thresh) { ok = FALSE_; io___12.ciunit = *nout; s_wsfe(&io___12); do_fio(&c__1, (char *)&rtrsyl, (ftnlen)sizeof(doublereal)); do_fio(&c__1, (char *)<rsyl, (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ntrsyl, (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ktrsyl, (ftnlen)sizeof(integer)); e_wsfe(); } zget36_(&rtrexc, <rexc, &ntrexc, &ktrexc, nin); if (rtrexc > *thresh || ntrexc > 0) { ok = FALSE_; io___17.ciunit = *nout; s_wsfe(&io___17); do_fio(&c__1, (char *)&rtrexc, (ftnlen)sizeof(doublereal)); do_fio(&c__1, (char *)<rexc, (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ntrexc, (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ktrexc, (ftnlen)sizeof(integer)); e_wsfe(); } zget37_(rtrsna, ltrsna, ntrsna, &ktrsna, nin); if (rtrsna[0] > *thresh || rtrsna[1] > *thresh || ntrsna[0] != 0 || ntrsna[1] != 0 || ntrsna[2] != 0) { ok = FALSE_; io___22.ciunit = *nout; s_wsfe(&io___22); do_fio(&c__3, (char *)&rtrsna[0], (ftnlen)sizeof(doublereal)); do_fio(&c__3, (char *)<rsna[0], (ftnlen)sizeof(integer)); do_fio(&c__3, (char *)&ntrsna[0], (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ktrsna, (ftnlen)sizeof(integer)); e_wsfe(); } zget38_(rtrsen, ltrsen, ntrsen, &ktrsen, nin); if (rtrsen[0] > *thresh || rtrsen[1] > *thresh || ntrsen[0] != 0 || ntrsen[1] != 0 || ntrsen[2] != 0) { ok = FALSE_; io___27.ciunit = *nout; s_wsfe(&io___27); do_fio(&c__3, (char *)&rtrsen[0], (ftnlen)sizeof(doublereal)); do_fio(&c__3, (char *)<rsen[0], (ftnlen)sizeof(integer)); do_fio(&c__3, (char *)&ntrsen[0], (ftnlen)sizeof(integer)); do_fio(&c__1, (char *)&ktrsen, (ftnlen)sizeof(integer)); e_wsfe(); } ntests = ktrsyl + ktrexc + ktrsna + ktrsen; if (ok) { io___29.ciunit = *nout; s_wsfe(&io___29); do_fio(&c__1, path, (ftnlen)3); do_fio(&c__1, (char *)&ntests, (ftnlen)sizeof(integer)); e_wsfe(); } return 0; /* End of ZCHKEC */ } /* zchkec_ */
