void check (const Matrix &A, Vector &x, const Vector &b) const
 Check data for linear system.

real residual (const Matrix &A, Vector &x, const Vector &b) const
 Compute l2-norm of residual.

void iterate (const Matrix &A, Vector &x, const Vector &b, real tol, unsigned int maxiter)
virtual void iteration (const Matrix &A, Vector &x, const Vector &b)

Detailed Description

The class LinearSolver serves as a base class for all linear solvers and provides a number of utilites to simplify the implementation of iterative methods.

A linear solver solves (approximately) a linear system Ax = b for a given right-hand side b.

Member Function Documentation

void LinearSolver::check (  const Matrix &  A,
Vector &  x,
const Vector &  b
)  const [protected]
 

Check data for linear system.

void LinearSolver::iterate (  const Matrix &  A,
Vector &  x,
const Vector &  b,
real  tol,
unsigned int  maxiter
)  [protected]
 

Iterative solution of the linear system. The virtual function iteration() is called in each iteration and should be implemented by a subclass making use of this function.

void LinearSolver::iteration (  const Matrix &  A,
Vector &  x,
const Vector &  b
)  [protected, virtual]
 

Perform one iteration on the linear system.

real LinearSolver::residual (  const Matrix &  A,
Vector &  x,
const Vector &  b
)  const [protected]
 

Compute l2-norm of residual.
