*>
|

*> (1) | A - Z D Z' | / ( |A| n ulp )

|
*> eigenvector option is given and D1 and D2 are the eigenvalues
|
||
|
*> returned with and without the eigenvector option.
|
||
|
*>
|
||
|
*> The "sizes" are specified by an array NN(1:NSIZES); the value of

*> 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.

|

|
*> NSIZES INTEGER
|
||
|
*> The number of sizes of matrices to use. If it is zero,
|
||
|
*> CDRVST 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, CDRVST
|
||
|
*> 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 CDRVST 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
|

|
