Module Contents

class pymor.bindings.dunegdt.DuneXTMatrixOperator(matrix, solver_options=None, name=None)

Bases: pymor.operators.list.LinearComplexifiedListVectorArrayOperatorBase

Wraps a dune-xt matrix as an Operator.

Parameters

matrix

The actual matrix from dune.xt.la, usually IstlMatrix.

solver_options

If specified, either a string or a dict specifying the solver used in apply_inverse. See https://zivgitlab.uni-muenster.de/ag-ohlberger/dune-community/dune-xt/-/tree/master/dune/xt/la/solver for available options, depending on the type of matrix. E.g., for dune.xt.la.IstlSparseMatrix, (as can be queried from dune.xt.la.IstlSparseMatrixSolver via types() and options(type)): - ‘bicgstab.ssor’ - ‘bicgstab.amg.ssor’ - ‘bicgstab.amg.ilu0’ - ‘bicgstab.ilut’ - ‘bicgstab’ - ‘cg’

name

Optional name of the resulting Operator.

linear = True
