/*            = .TRUE.  if they are to be compared */

/*          described above, exceeds THRESH.  Note that the error */
/*          is scaled to be O(1), so THRESH should be a reasonably */
/*          small multiple of 1, e.g., 10 or 100.  In particular, */
/*          it should not depend on the precision (single vs. double) */

/*  WTMP    (workspace) COMPLEX*16 array, dimension (N) */

/*          When COMP = .TRUE. RCDVIN holds the precomputed reciprocal */
/*          condition number for the selected right invariant subspace. */

/*  NSLCT   (input) INTEGER */
/*          When COMP = .TRUE. the number of selected eigenvalues */
/*          corresponding to the precomputed values RCDEIN and RCDVIN. */

/*  ISLCT   (input) INTEGER array, dimension (NSLCT) */
/*          When COMP = .TRUE. ISLCT selects the eigenvalues of the */
/*          input matrix corresponding to the precomputed values RCDEIN */
/*          and RCDVIN. For I=1, ... ,NSLCT, if ISLCT(I) = J, then the */
/*          eigenvalue with the J-th largest real or imaginary part is */
/*          selected. The real part is used if ISRT = 0, and the */
/*          imaginary part if ISRT = 1. */
/*          Not referenced if COMP = .FALSE. */

/*  ISRT    (input) INTEGER */
/*          When COMP = .TRUE., ISRT describes how ISLCT is used to */
