*  Purpose
*  =======
*
*     ZGET24 checks the nonsymmetric eigenvalue (Schur form) problem
*     expert driver ZGEESX.
*
*     If COMP = .FALSE., the first 13 of the following tests will be
*     be performed on the input matrix A, and also tests 14 and 15
*     if LWORK is sufficiently large.
*     If COMP = .TRUE., all 17 test will be performed.
*
*     (1)     0 if T is in Schur form, 1/ulp otherwise
*            (no sorting of eigenvalues)
*
*     (2)     | A - VS T VS' | / ( n |A| ulp )
*
*       Here VS is the matrix of Schur eigenvectors, and T is in Schur
*       form  (no sorting of eigenvalues).
*
*     (3)     | I - VS VS' | / ( n ulp ) (no sorting of eigenvalues).
*
*     (4)     0     if W are eigenvalues of T
*             1/ulp otherwise
*             (no sorting of eigenvalues)
*
*     (5)     0     if T(with VS) = T(without VS),
*             1/ulp otherwise
*             (no sorting of eigenvalues)
*
*     (6)     0     if eigenvalues(with VS) = eigenvalues(without VS),
*             1/ulp otherwise
*             (no sorting of eigenvalues)
*
*     (7)     0 if T is in Schur form, 1/ulp otherwise
*             (with sorting of eigenvalues)
*
*     (8)     | A - VS T VS' | / ( n |A| ulp )
*
*       Here VS is the matrix of Schur eigenvectors, and T is in Schur
*       form  (with sorting of eigenvalues).
*
*     (9)     | I - VS VS' | / ( n ulp ) (with sorting of eigenvalues).
*
*     (10)    0     if W are eigenvalues of T
*             1/ulp otherwise
*             If workspace sufficient, also compare W with and
*             without reciprocal condition numbers
*             (with sorting of eigenvalues)
*
*     (11)    0     if T(with VS) = T(without VS),
*             1/ulp otherwise
*             If workspace sufficient, also compare T with and without
*             reciprocal condition numbers
*             (with sorting of eigenvalues)
*
*     (12)    0     if eigenvalues(with VS) = eigenvalues(without VS),
*             1/ulp otherwise
*             If workspace sufficient, also compare VS with and without
*             reciprocal condition numbers
*             (with sorting of eigenvalues)
*
*     (13)    if sorting worked and SDIM is the number of
*             eigenvalues which were SELECTed
*             If workspace sufficient, also compare SDIM with and
*             without reciprocal condition numbers
*
*     (14)    if RCONDE the same no matter if VS and/or RCONDV computed
*
*     (15)    if RCONDV the same no matter if VS and/or RCONDE computed

*
*        RCONDE is the reciprocal average eigenvalue condition number
*        computed by ZGEESX and RCDEIN (the precomputed true value)
*        is supplied as input.  cond(RCONDE) is the condition number
*        of RCONDE, and takes errors in computing RCONDE into account,
*        so that the resulting quantity should be O(ULP). cond(RCONDE)
*        is essentially given by norm(A)/RCONDV.
*
*     (17)  |RCONDV - RCDVIN| / cond(RCONDV)
*
*        RCONDV is the reciprocal right invariant subspace condition
*        number computed by ZGEESX and RCDVIN (the precomputed true
*        value) is supplied as input. cond(RCONDV) is the condition
*        number of RCONDV, and takes errors in computing RCONDV into
*        account, so that the resulting quantity should be O(ULP).
*        cond(RCONDV) is essentially given by norm(A)/RCONDE.
*
*  Arguments
*  =========
*
*  COMP    (input) LOGICAL
*          COMP describes which input tests to perform:
*            = .FALSE. if the computed condition numbers are not to
*                      be tested against RCDVIN and RCDEIN
*            = .TRUE.  if they are to be compared
*
*  JTYPE   (input) INTEGER
*          Type of input matrix. Used to label output if error occurs.
*
*  ISEED   (input) INTEGER array, dimension (4)
*          If COMP = .FALSE., the random number generator seed
*          used to produce matrix.
*          If COMP = .TRUE., ISEED(1) = the number of the example.
*          Used to label output if error occurs.
*
*  THRESH  (input) DOUBLE PRECISION
*          A test will count as "failed" if the "error", computed as
*          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)
*          or the size of the matrix.  It must be at least zero.
*
*  NOUNIT  (input) INTEGER
*          The FORTRAN unit number for printing out error messages
*          (e.g., if a routine returns INFO not equal to 0.)
*
*  N       (input) INTEGER
*          The dimension of A. N must be at least 0.
*
*  A       (input/output) COMPLEX*16 array, dimension (LDA, N)
*          Used to hold the matrix whose eigenvalues are to be
*          computed.
*
*  LDA     (input) INTEGER
*          The leading dimension of A, and H. LDA must be at
*          least 1 and at least N.
*
*  H       (workspace) COMPLEX*16 array, dimension (LDA, N)
*          Another copy of the test matrix A, modified by ZGEESX.
*
*  HT      (workspace) COMPLEX*16 array, dimension (LDA, N)
*          Yet another copy of the test matrix A, modified by ZGEESX.
*
*  W       (workspace) COMPLEX*16 array, dimension (N)
*          The computed eigenvalues of A.
*
*  WT      (workspace) COMPLEX*16 array, dimension (N)
*          Like W, this array contains the eigenvalues of A,
*          but those computed when ZGEESX only computes a partial
*          eigendecomposition, i.e. not Schur vectors
*
*  WTMP    (workspace) COMPLEX*16 array, dimension (N)
*          Like W, this array contains the eigenvalues of A,
*          but sorted by increasing real or imaginary part.

*          VS holds the computed Schur vectors.
*
*  LDVS    (input) INTEGER
*          Leading dimension of VS. Must be at least max(1, N).
*
*  VS1     (workspace) COMPLEX*16 array, dimension (LDVS, N)
*          VS1 holds another copy of the computed Schur vectors.
*
*  RCDEIN  (input) DOUBLE PRECISION
*          When COMP = .TRUE. RCDEIN holds the precomputed reciprocal
*          condition number for the average of selected eigenvalues.
*
*  RCDVIN  (input) DOUBLE PRECISION
*          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

*          Not referenced if COMP = .FALSE.
*
*  RESULT  (output) DOUBLE PRECISION array, dimension (17)
*          The values computed by the 17 tests described above.
*          The values are currently limited to 1/ulp, to avoid
*          overflow.
*
*  WORK    (workspace) COMPLEX*16 array, dimension (2*N*N)
*
*  LWORK   (input) INTEGER
*          The number of entries in WORK to be passed to ZGEESX. This
*          must be at least 2*N, and N*(N+1)/2 if tests 14--16 are to
*          be performed.
*
*  RWORK   (workspace) DOUBLE PRECISION array, dimension (N)
*
*  BWORK   (workspace) LOGICAL array, dimension (N)
*
*  INFO    (output) INTEGER
*          If 0,  successful exit.
*          If <0, input parameter -INFO had an incorrect value.
*          If >0, ZGEESX returned an error code, the absolute
*                 value of which is returned.
