SGET37 tests STRSNA, a routine for estimating condition numbers of


 eigenvalues and/or right eigenvectors of a matrix.


 The test matrices are read from a file with logical unit number NIN.

RMAX

          RMAX is REAL array, dimension (3)


          Value of the largest test ratio.


          RMAX(1) = largest ratio comparing different calls to STRSNA


          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 STRSNA 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 STRSNA returned INFO nonzero

KNT

          KNT is INTEGER


          Total number of examples tested.

NIN

          NIN is INTEGER


          Input logical unit number
