Purpose:
Verifies and prints a permutation vector.
Returns:
UMFPACK_OK if Control [UMFPACK_PRL] <= 2 (the input is not checked).
Otherwise:
UMFPACK_OK if the permutation vector is valid (this includes that case
when Perm is (Int *) NULL, which is not an error condition).
UMFPACK_ERROR_n_nonpositive if np <= 0.
UMFPACK_ERROR_out_of_memory if out of memory.
UMFPACK_ERROR_invalid_permutation if Perm is not a valid permutation vector.
Arguments:
Int np ; Input argument, not modified.
Perm is an integer vector of size np. Restriction: np > 0.
Int Perm [np] ; Input argument, not modified.
A permutation vector of size np. If Perm is not present (an (Int *)
NULL pointer), then it is assumed to be the identity permutation. This
is consistent with its use as an input argument to umfpack_*_qsymbolic,
and is not an error condition. If Perm is present, the entries in Perm
must range between 0 and np-1, and no duplicates may exist.
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
