SCHKEC
SCHKEC tests eigen- condition estimation routines SLALN2, SLASY2, SLANV2, SLAQTR, SLAEXC, STRSYL, STREXC, STRSNA, STRSEN 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, STREXC, STRSNA and STRSEN are tested by reading in precomputed examples from a file (on input unit NIN). Output is written to output unit NOUT.
[in] | THRESH | THRESH is REAL Threshold for residual tests. A computed test ratio passes the threshold if it is less than THRESH. |
[in] | TSTERR | TSTERR is LOGICAL Flag that indicates whether error exits are to be tested. |
[in] | NIN | NIN is INTEGER The logical unit number for input. |
[in] | NOUT | NOUT is INTEGER The logical unit number for output. |
