Purpose:
Verifies and prints a Numeric object (the LU factorization, both its pattern
numerical values, and permutation vectors P and Q). This routine checks the
object more carefully than the computational routines. Normally, this check
is not required, since umfpack_*_numeric either returns (void *) NULL, or a
valid Numeric object. However, if you suspect that your own code has
corrupted the Numeric object (by overruning memory bounds, for example),
then this routine might be able to detect a corrupted Numeric object. Since
this is a complex object, not all such user-generated errors are guaranteed
to be caught by this routine.
Returns:
UMFPACK_OK if Control [UMFPACK_PRL] <= 2 (the input is not checked).
Otherwise:
UMFPACK_OK if the Numeric object is valid.
UMFPACK_ERROR_invalid_Numeric_object if the Numeric object is invalid.
UMFPACK_ERROR_out_of_memory if out of memory.
Arguments:
void *Numeric ; Input argument, not modified.
The Numeric object, which holds the numeric factorization computed by
umfpack_*_numeric.
double Control [UMFPACK_CONTROL] ; Input argument, not modified.
If a (double *) NULL pointer is passed, then the default control
settings are used. Otherwise, the settings are determined from the
Control array. See umfpack_*_defaults on how to fill the Control
array with the default settings. If Control contains NaN's, the
defaults are used. The following Control parameters are used:
Control [UMFPACK_PRL]: printing level.
2 or less: no output. returns silently without checking anything.
3: fully check input, and print a short summary of its status
4: as 3, but print first few entries of the input
5: as 3, but print all of the input
Default: 1
