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.
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))
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
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
KNT
KNT is INTEGER
Total number of examples tested.
NIN
NIN is INTEGER
Input logical unit number.
