DirectSolverFactorizationInfo#

class nvmath.sparse.advanced.DirectSolverFactorizationInfo(solver)[source]#

An interface to query information returned by nvmath.sparse.advanced.DirectSolver.factorize().

Methods

__init__(solver)[source]#: ctor for internal use only.

Attributes

col_permutation#: Query the column permutation after factorization. See the cuDSS documentation for more information.

diag#: Query the diagonal of the factorized system. See the cuDSS documentation for more information.

inertia#: Query the inertia (number of positive and negative pivots) encountered in the LU factorization. See the cuDSS documentation for more information.

info#: Query the error info after factorization. See the cuDSS documentation for more information.

lu_nnz#: Query the number of non-zeros in the LU factorization. See the cuDSS documentation for more information.

npivots#: Query the number of pivots encountered in the LU factorization. See the cuDSS documentation for more information.

row_permutation#: Query the row permutation after factorization. See the cuDSS documentation for more information.
