SGET38
SGET38 tests STRSEN, 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 REAL array, dimension (3) Values of the largest test ratios. RMAX(1) = largest residuals from SHST01 or comparing different calls to STRSEN 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 SGEHRD returns INFO nonzero on example i, LMAX(1)=i If SHSEQR returns INFO nonzero on example i, LMAX(2)=i If STRSEN returns INFO nonzero on example i, LMAX(3)=i |
[out] | NINFO | NINFO is INTEGER array, dimension (3) NINFO(1) = No. of times SGEHRD returned INFO nonzero NINFO(2) = No. of times SHSEQR returned INFO nonzero NINFO(3) = No. of times STRSEN returned INFO nonzero |
[out] | KNT | KNT is INTEGER Total number of examples tested. |
[in] | NIN | NIN is INTEGER Input logical unit number. |
