pymatsolver.SolverLU#

class pymatsolver.SolverLU(A, is_symmetric=None, is_positive_definite=False, is_hermitian=None, check_accuracy=False, check_rtol=1e-06, check_atol=0, **kwargs)[source]#

Wrapped SolverLU solver, using scipy.sparse.linalg.splu.

The transposed solver (.T) re-uses this solver’s LU factorization instead of factoring A.T. Transposed and conjugated solvers share this factorization, and are updated along with it when it is re-factored.

Parameters:

A: The matrix to use for the solver.
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.
check_accuracybool, optional: Whether to check the accuracy of the solution.
check_rtolfloat, optional: The relative tolerance to check against for accuracy.
check_atolfloat, optional: The absolute tolerance to check against for accuracy.
**kwargs: Extra keyword arguments which will attempted to be passed to scipy.sparse.linalg.splu.

Attributes:

A: The matrix to solve with.
T: The transposed solve operator
check_accuracy: Whether the check the accuracy after a solve.
check_atol: The absolute tolerance used to check the solve operation.
check_rtol: The relative tolerance used to check the solve operation.
dtype: The data type of the matrix.
is_hermitian: Whether the matrix is hermitian.
is_positive_definite: Whether the matrix is positive definite.
is_real: Whether the matrix is real.
is_symmetric: Whether the matrix is symmetric.
shape: The input matrix dimensions.
solver: The underlying solver object shared by this solver’s transposed and conjugated views.
