/*     February 2007 */

/*     .. Scalar Arguments .. */
/*     .. */
/*     .. Array Arguments .. */
/*     .. */

/*  Purpose */
/*  ======= */

/*     CCHKHS  checks the nonsymmetric eigenvalue problem routines. */

/*             CGEHRD factors A as  U H U' , where ' means conjugate */
/*             transpose, H is hessenberg, and U is unitary. */

/*             CUNGHR generates the unitary matrix U. */

/*             CUNMHR multiplies a matrix by the unitary matrix U. */

/*             CHSEQR factors H as  Z T Z' , where Z is unitary and T */
/*             is upper triangular.  It also computes the eigenvalues, */
/*             w(1), ..., w(n); we define a diagonal matrix W whose */
/*             (diagonal) entries are the eigenvalues. */

/*             CTREVC computes the left eigenvector matrix L and the */
/*             right eigenvector matrix R for the matrix T.  The */
/*             columns of L are the complex conjugates of the left */
/*             eigenvectors of T.  The columns of R are the right */
/*             eigenvectors of T.  L is lower triangular, and R is */
/*             upper triangular. */

/*             CHSEIN computes the left eigenvector matrix Y and the */
/*             right eigenvector matrix X for the matrix H.  The */
/*             columns of Y are the complex conjugates of the left */
/*             eigenvectors of H.  The columns of X are the right */
/*             eigenvectors of H.  Y is lower triangular, and X is */
/*             upper triangular. */

/*     When CCHKHS is called, a number of matrix "sizes" ("n's") and a */
/*     number of matrix "types" are specified.  For each size ("n") */
/*     and each type of matrix, one matrix will be generated and used */
/*     to test the nonsymmetric eigenroutines.  For each matrix, 14 */
/*     tests will be performed: */

/*     (1)     | A - U H U**H | / ( |A| n ulp ) */

/*     (2)     | I - UU**H | / ( n ulp ) */

/*     (3)     | H - Z T Z**H | / ( |H| n ulp ) */

/*     (4)     | I - ZZ**H | / ( n ulp ) */

/*     (5)     | A - UZ H (UZ)**H | / ( |A| n ulp ) */

/*     (6)     | I - UZ (UZ)**H | / ( n ulp ) */

/*     (7)     | T(Z computed) - T(Z not computed) | / ( |T| ulp ) */

/*     (8)     | W(Z computed) - W(Z not computed) | / ( |W| ulp ) */

/*     (9)     | TR - RW | / ( |T| |R| ulp ) */

/*     (10)    | L**H T - W**H L | / ( |T| |L| ulp ) */

/*     (11)    | HX - XW | / ( |H| |X| ulp ) */

/*     (12)    | Y**H H - W**H Y | / ( |H| |Y| ulp ) */

/*     (13)    | AX - XW | / ( |A| |X| ulp ) */

/*     (14)    | Y**H A - W**H Y | / ( |A| |Y| ulp ) */

/*     The "sizes" are specified by an array NN(1:NSIZES); the value of */
/*     each element NN(j) specifies one size. */
/*     The "types" are specified by a logical array DOTYPE( 1:NTYPES ); */
/*     if DOTYPE(j) is .TRUE., then matrix type "j" will be generated. */
/*     Currently, the list of possible types is: */

/*     (1)  The zero matrix. */
/*     (2)  The identity matrix. */
/*     (3)  A (transposed) Jordan block, with 1's on the diagonal. */

/*     (4)  A diagonal matrix with evenly spaced entries */
/*          1, ..., ULP  and random complex angles. */
/*          (ULP = (first number larger than 1) - 1 ) */
/*     (5)  A diagonal matrix with geometrically spaced entries */
/*          1, ..., ULP  and random complex angles. */
/*     (6)  A diagonal matrix with "clustered" entries 1, ULP, ..., ULP */
/*          and random complex angles. */

/*     (7)  Same as (4), but multiplied by SQRT( overflow threshold ) */
/*     (8)  Same as (4), but multiplied by SQRT( underflow threshold ) */

/*     (9)  A matrix of the form  U' T U, where U is unitary and */
/*          T has evenly spaced entries 1, ..., ULP with random complex */

/*     (12) A matrix of the form  U' T U, where U is unitary and */
/*          T has complex eigenvalues randomly chosen from */
/*          ULP < |z| < 1   and random O(1) entries in the upper */
/*          triangle. */

/*     (13) A matrix of the form  X' T X, where X has condition */
/*          SQRT( ULP ) and T has evenly spaced entries 1, ..., ULP */
/*          with random complex angles on the diagonal and random O(1) */
/*          entries in the upper triangle. */

/*     (14) A matrix of the form  X' T X, where X has condition */
/*          SQRT( ULP ) and T has geometrically spaced entries */
/*          1, ..., ULP with random complex angles on the diagonal */
/*          and random O(1) entries in the upper triangle. */

/*     (15) A matrix of the form  X' T X, where X has condition */

/*          entries in the upper triangle. */

/*     (16) A matrix of the form  X' T X, where X has condition */

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

/*  NSIZES - INTEGER */
/*           The number of sizes of matrices to use.  If it is zero, */
/*           CCHKHS does nothing.  It must be at least zero. */
/*           Not modified. */

/*  NN     - INTEGER array, dimension (NSIZES) */
/*           An array containing the sizes to be used for the matrices. */
/*           Zero values will be skipped.  The values must be at least */
/*           zero. */
/*           Not modified. */

/*  NTYPES - INTEGER */
/*           The number of elements in DOTYPE.   If it is zero, CCHKHS */
/*           does nothing.  It must be at least zero.  If it is MAXTYP+1 */
/*           and NSIZES is 1, then an additional type, MAXTYP+1 is */
/*           defined, which is to use whatever matrix is in A.  This */
/*           is only useful if DOTYPE(1:MAXTYP) is .FALSE. and */
/*           DOTYPE(MAXTYP+1) is .TRUE. . */
/*           Not modified. */

/*  DOTYPE - LOGICAL array, dimension (NTYPES) */
/*           If DOTYPE(j) is .TRUE., then for each size in NN a */
/*           matrix of that size and of type j will be generated. */
/*           If NTYPES is smaller than the maximum number of types */
/*           defined (PARAMETER MAXTYP), then types NTYPES+1 through */
/*           MAXTYP will not be generated.  If NTYPES is larger */
/*           than MAXTYP, DOTYPE(MAXTYP+1) through DOTYPE(NTYPES) */
/*           will be ignored. */
/*           Not modified. */

/*  ISEED  - INTEGER array, dimension (4) */
/*           On entry ISEED specifies the seed of the random number */
/*           generator. The array elements should be between 0 and 4095; */
/*           if not they will be reduced mod 4096.  Also, ISEED(4) must */
/*           be odd.  The random number generator uses a linear */
/*           congruential sequence limited to small integers, and so */
/*           should produce machine independent random numbers. The */
/*           values of ISEED are changed on exit, and can be used in the */
/*           next call to CCHKHS to continue the same random number */
/*           sequence. */
/*           Modified. */

/*  THRESH - REAL */
/*           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. */
/*           Not modified. */

/*  NOUNIT - INTEGER */
/*           The FORTRAN unit number for printing out error messages */
/*           (e.g., if a routine returns IINFO not equal to 0.) */
/*           Not modified. */

/*  A      - COMPLEX array, dimension (LDA,max(NN)) */
/*           Used to hold the matrix whose eigenvalues are to be */
/*           computed.  On exit, A contains the last matrix actually */
/*           used. */
/*           Modified. */

/*  LDA    - INTEGER */
/*           The leading dimension of A, H, T1 and T2.  It must be at */
/*           least 1 and at least max( NN ). */
/*           Not modified. */

/*  H      - COMPLEX array, dimension (LDA,max(NN)) */
/*           The upper hessenberg matrix computed by CGEHRD.  On exit, */
/*           H contains the Hessenberg form of the matrix in A. */
/*           Modified. */

/*  T1     - COMPLEX array, dimension (LDA,max(NN)) */
/*           The Schur (="quasi-triangular") matrix computed by CHSEQR */
/*           if Z is computed.  On exit, T1 contains the Schur form of */
/*           the matrix in A. */
/*           Modified. */

/*  T2     - COMPLEX array, dimension (LDA,max(NN)) */
