NAME
       TESTING/EIG/sget37.f

SYNOPSIS
   Functions/Subroutines
       subroutine sget37 (rmax, lmax, ninfo, knt, nin)
           SGET37

Function/Subroutine Documentation
   subroutine sget37 (real, dimension( 3 ) rmax, integer, dimension( 3 ) lmax,
       integer, dimension( 3 ) ninfo, integer knt, integer nin)
       SGET37

       Purpose:


            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.

       Parameters
           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
