Francesco Lannutti 23e91d22e6 Changed the PivTol in SMPreorder with PivRel 2023-05-06 01:46:04 +02:00
Francesco Lannutti 36dbc7c626 Changed the Error message in klusmp.c to Information 2023-05-06 01:46:04 +02:00
Francesco Lannutti 4c993548ed Getting rid of SPARSE for Initial Circuit Matrix creation. Now KLU is totally independent from SPARSE. This opens up the interface for other solvers as well 
SPARSE can still used through '.options sparse', but it isn't possible to switch from KLU to SPARSE and viceversa at run-time

Francesco Lannutti 8de9e72f12 Handled the SINGULAR matrix case in a more clever way! 2023-05-06 01:46:04 +02:00
Francesco Lannutti 48572883f9 Fixed again the NIiter loop for KLU 2023-05-06 01:46:04 +02:00
Francesco Lannutti d7f5e3863e Fixed KLU returns values so that NIiter can Factor again, if the matrix is numerically singular from the refactorization 
Fixed the NIiter code to perform a factorization without reloading the matrix

Francesco Lannutti af804b3c7d Fixed the KLU returns values for Factorization and ReFactorization. 
If the matrix is Numerically Singular, continue the factorization till the end
