pymatsolver.Forward

class pymatsolver.Forward(A, check_accuracy=False, check_rtol=1e-06, check_atol=0, accuracy_tol=None, **kwargs)

A solver for a lower triangular matrix.

Parameters:

Ascipy.sparse.sparray or scipy.sparse.spmatrix

The lower triangular matrix to solve.

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.

accuracy_tolfloat, 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 passed to the base class.

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.
