Detailed Description
This class defines a common interface for linear operators, including actual matrices (class GenericMatrix) and linear operators only defined in terms of their action on vectors.
This class is used internally by DOLFIN to define a class hierarchy of backend independent linear operators and solvers. Users should not interface to this class directly but instead use the LinearOperator class.

◆ init_layout()
|
inlineprotectedvirtual |
Initialize linear operator to match parallel layout of vectors x and y for product y = Ax. Needs to be implemented by backend.
Reimplemented in dolfin::PETScLinearOperator.
