ZGET38
ZGET38 tests ZTRSEN, a routine for estimating condition numbers of a cluster of eigenvalues and/or its associated right invariant subspace The test matrices are read from a file with logical unit number NIN.
| [out] | RMAX | RMAX is DOUBLE PRECISION array, dimension (3)
Values of the largest test ratios.
RMAX(1) = largest residuals from ZHST01 or comparing
different calls to ZTRSEN
RMAX(2) = largest error in reciprocal condition
numbers taking their conditioning into account
RMAX(3) = largest error in reciprocal condition
numbers not taking their conditioning into
account (may be larger than RMAX(2)) |
| [out] | LMAX | LMAX is INTEGER array, dimension (3)
LMAX(i) is example number where largest test ratio
RMAX(i) is achieved. Also:
If ZGEHRD returns INFO nonzero on example i, LMAX(1)=i
If ZHSEQR returns INFO nonzero on example i, LMAX(2)=i
If ZTRSEN returns INFO nonzero on example i, LMAX(3)=i |
| [out] | NINFO | NINFO is INTEGER array, dimension (3)
NINFO(1) = No. of times ZGEHRD returned INFO nonzero
NINFO(2) = No. of times ZHSEQR returned INFO nonzero
NINFO(3) = No. of times ZTRSEN returned INFO nonzero |
| [out] | KNT | KNT is INTEGER
Total number of examples tested. |
| [in] | NIN | NIN is INTEGER
Input logical unit number. |
