/*  ======= */

/*  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. */

/*  Arguments */
/*  ========== */

/*  RMAX    (output) 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    (output) 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   (output) 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     (output) INTEGER */
/*          Total number of examples tested. */
