pymatsolver.Pardiso#
- class pymatsolver.Pardiso(A, n_threads=None, is_symmetric=None, is_positive_definite=False, is_hermitian=None, check_accuracy=False, check_rtol=1e-06, check_atol=0, accuracy_tol=None, **kwargs)[source]#
The Pardiso direct solver.
This solver uses the pydiso Intel MKL wrapper to factorize a sparse matrix, and use that factorization for solving.
- Parameters:
- A
scipy.sparse.spmatrix
Matrix to solve with.
- n_threads
int
,optional
Number of threads to use for the Pardiso routine in Intel’s MKL.
- is_symmetricbool,
optional
Whether the matrix is symmetric. By default, it will perform some simple tests to check for symmetry, and default to
False
if those fail.- is_positive_definitebool,
optional
Whether the matrix is positive definite.
- is_hermitianbool,
optional
Whether the matrix is hermitian. By default, it will perform some simple tests to check, and default to
False
if those fail.- check_accuracybool,
optional
Whether to check the accuracy of the solution.
- check_rtol
float
,optional
The relative tolerance to check against for accuracy.
- check_atol
float
,optional
The absolute tolerance to check against for accuracy.
- accuracy_tol
float
,optional
Relative accuracy tolerance. .. deprecated:: 0.3.0
accuracy_tol will be removed in pymatsolver 0.4.0. Use check_rtol and check_atol instead.
- **kwargs
Extra keyword arguments. If there are any left here a warning will be raised.
- A

n_threads
Number of threads to use for the Pardiso solver routine.
shape
The input matrix dimensions.
