/*  -- LAPACK test routine (version 3.1) -- */

/*     November 2006 */

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

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

/*  CCHKST  checks the Hermitian eigenvalue problem routines. */

/*     CHETRD factors A as  U S U* , where * means conjugate transpose, */
/*     S is real symmetric tridiagonal, and U is unitary. */
/*     CHETRD can use either just the lower or just the upper triangle */
/*     of A; CCHKST checks both cases. */
/*     U is represented as a product of Householder */
/*     transformations, whose vectors are stored in the first */
/*     n-1 columns of V, and whose scale factors are in TAU. */

/*     CHPTRD does the same as CHETRD, except that A and V are stored */
/*     in "packed" format. */

/*     CUNGTR constructs the matrix U from the contents of V and TAU. */

/*     CUPGTR constructs the matrix U from the contents of VP and TAU. */

/*     CSTEQR factors S as  Z D1 Z* , where Z is the unitary */
/*     matrix of eigenvectors and D1 is a diagonal matrix with */
/*     the eigenvalues on the diagonal.  D2 is the matrix of */
/*     eigenvalues computed when Z is not computed. */

/*     SSTERF computes D3, the matrix of eigenvalues, by the */
/*     PWK method, which does not yield eigenvectors. */

/*     CPTEQR factors S as  Z4 D4 Z4* , for a */
/*     Hermitian positive definite tridiagonal matrix. */
/*     D5 is the matrix of eigenvalues computed when Z is not */
/*     computed. */

/*     SSTEBZ computes selected eigenvalues.  WA1, WA2, and */
/*     WA3 will denote eigenvalues computed to high */
/*     absolute accuracy, with different range options. */
/*     WR will denote eigenvalues computed to high relative */
/*     accuracy. */

/*     CSTEIN computes Y, the eigenvectors of S, given the */
/*     eigenvalues. */

/*     CSTEDC factors S as Z D1 Z* , where Z is the unitary */
/*     matrix of eigenvectors and D1 is a diagonal matrix with */
/*     the eigenvalues on the diagonal ('I' option). It may also */
/*     update an input unitary matrix, usually the output */
/*     from CHETRD/CUNGTR or CHPTRD/CUPGTR ('V' option). It may */
/*     also just compute eigenvalues ('N' option). */

/*     CSTEMR factors S as Z D1 Z* , where Z is the unitary */
/*     matrix of eigenvectors and D1 is a diagonal matrix with */
/*     the eigenvalues on the diagonal ('I' option).  CSTEMR */
/*     uses the Relatively Robust Representation whenever possible. */

/*  When CCHKST 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 Hermitian eigenroutines.  For each matrix, a number */
/*  of tests will be performed: */

/*  (1)     | A - V S V* | / ( |A| n ulp ) CHETRD( UPLO='U', ... ) */

/*  (2)     | I - UV* | / ( n ulp )        CUNGTR( UPLO='U', ... ) */

/*  (3)     | A - V S V* | / ( |A| n ulp ) CHETRD( UPLO='L', ... ) */

/*  (4)     | I - UV* | / ( n ulp )        CUNGTR( UPLO='L', ... ) */

/*  (5-8)   Same as 1-4, but for CHPTRD and CUPGTR. */

/*  (9)     | S - Z D Z* | / ( |S| n ulp ) CSTEQR('V',...) */

/*  (10)    | I - ZZ* | / ( n ulp )        CSTEQR('V',...) */

/*  (12)    | D1 - D3 | / ( |D1| ulp )        SSTERF */

/*  (13)    0 if the true eigenvalues (computed by sturm count) */
/*          of S are within THRESH of */

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

/*  NSIZES  (input) INTEGER */
/*          The number of sizes of matrices to use.  If it is zero, */
/*          CCHKST does nothing.  It must be at least zero. */

/*  NN      (input) 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. */

/*  NTYPES  (input) INTEGER */
/*          The number of elements in DOTYPE.   If it is zero, CCHKST */
/*          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. . */

/*  DOTYPE  (input) 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. */

/*  ISEED   (input/output) 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 CCHKST to continue the same random number */
/*          sequence. */

/*  THRESH  (input) 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) */
