class pymor.operators.list.LinearComplexifiedListVectorArrayOperatorBase

Bases: ListVectorArrayOperatorBase

Base Operator for complexified ListVectorArrays.

class pymor.operators.list.ListVectorArrayOperatorBase

Bases: pymor.operators.interface.Operator

Base Operator for ListVectorArrays.

Methods

apply	Apply the operator to a VectorArray.
apply_adjoint	Apply the adjoint operator.

apply(U, mu=None)

Apply the operator to a VectorArray.

Parameters:

• U – VectorArray of vectors to which the operator is applied.

• mu – The parameter values for which to evaluate the operator.

Returns:

|VectorArray| of the operator evaluations.

apply_adjoint(V, mu=None)

Apply the adjoint operator.

For any given linear Operator op, parameter values mu and VectorArrays U, V in the source resp. range we have:

op.apply_adjoint(V, mu).dot(U) == V.inner(op.apply(U, mu))

Thus, when op is represented by a matrix M, apply_adjoint is given by left-multiplication of (the complex conjugate of) M with V.

Parameters:

• V – VectorArray of vectors to which the adjoint operator is applied.

• mu – The parameter values for which to apply the adjoint operator.

Returns:

|VectorArray| of the adjoint operator evaluations.

class pymor.operators.list.NumpyListVectorArrayMatrixOperator(matrix, solver=None, name=None)

Bases: ListVectorArrayOperatorBase, pymor.operators.numpy.NumpyMatrixOperator

Variant of NumpyMatrixOperator using ListVectorArray instead of NumpyVectorArray.

This class is mainly intended for performance tests of ListVectorArray. In general NumpyMatrixOperator should be used instead of this class.

Parameters:

• matrix – The NumPy array which is to be wrapped.

• solver – The Solver for the operator.

• name – Name of the operator.
