68 Purpose: |
|
|
69 |
|
|
70 Verifies and prints a Numeric object (the LU factorization, both its pattern |
|
|
71 numerical values, and permutation vectors P and Q). This routine checks the |
|
|
72 object more carefully than the computational routines. Normally, this check |
|
|
73 is not required, since umfpack_*_numeric either returns (void *) NULL, or a |
|
|
74 valid Numeric object. However, if you suspect that your own code has |
|
|
75 corrupted the Numeric object (by overruning memory bounds, for example), |
|
|
76 then this routine might be able to detect a corrupted Numeric object. Since |
|
|
77 this is a complex object, not all such user-generated errors are guaranteed |
|
|
78 to be caught by this routine. |
|
|
79 |
|
|
80 Returns: |
|
|
81 |
|
|
82 UMFPACK_OK if Control [UMFPACK_PRL] <= 2 (the input is not checked). |
|
|
83 |
|
|
84 Otherwise: |
|
|
85 |
|
|
86 UMFPACK_OK if the Numeric object is valid. |
|
|
87 UMFPACK_ERROR_invalid_Numeric_object if the Numeric object is invalid. |
|
|
88 UMFPACK_ERROR_out_of_memory if out of memory. |
|
|
89 |
|
|
90 Arguments: |
|
|
91 |
|
|
92 void *Numeric ; Input argument, not modified. |
|
|
93 |
|
|
94 The Numeric object, which holds the numeric factorization computed by |
|
|
95 umfpack_*_numeric. |
|
|
96 |
|
|
97 double Control [UMFPACK_CONTROL] ; Input argument, not modified. |
|
|
98 |
|
|
99 If a (double *) NULL pointer is passed, then the default control |
|
|
100 settings are used. Otherwise, the settings are determined from the |
|
|
101 Control array. See umfpack_*_defaults on how to fill the Control |
|
|
102 array with the default settings. If Control contains NaN's, the |
|
|
103 defaults are used. The following Control parameters are used: |
|
|
104 |
|
|
105 Control [UMFPACK_PRL]: printing level. |
|
|
106 |
|
|
107 2 or less: no output. returns silently without checking anything. |
|
|
108 3: fully check input, and print a short summary of its status |
|
|
109 4: as 3, but print first few entries of the input |
|
|
110 5: as 3, but print all of the input |
|
|
111 Default: 1 |
