Introduction

This doxygen collection documents a set of interfaces for linear operators to which a solver can be applied to solve, in some sense, a linear system of equations. These linear operators are derived from or extend the Fundamental Thyra ANA Operator/Vector Interfaces. These interfaces comprise the basic interface to linear equation solvers. Below we use the term "forward" to denote the original operator to which a solver is associated to distinguish it from the "inverse" operator.

Software

• Thyra::PreconditionerBase defines an interface to left, right, split left/right, and otherwise general preconditioners.

• Thyra::PreconditionerFactoryBase defines an interface for generating or updating a Thyra::PreconditionerBase object given a forward Thyra::LinearOpBase object.

• Thyra::LinearOpWithSolveBase defines a simple interface for performing the inverse linear operator application.

• Thyra::LinearOpWithSolveFactoryBase defines an interface for generating or updating a Thyra::LinearOpWithSolveBase object given a forward Thyra::LinearOpBase object.
