Detailed Description

Concrete class for a weighted L2 vector space.

This class allows users to override the inner product and norm used by the NOX::Epetra::Vector class. The most frequent use of this class is for introducing a weighted norm throughout NOX.

Member Function Documentation

double NOX::Epetra::VectorSpaceScaledL2::innerProduct (  const Epetra_Vector &  a,
const Epetra_Vector &  b
)  const [virtual]
 

Computes a scaled inner product.

Computes a scaled inner product: $ <Da, Db> $ where $D$ is the set of scaling vectors associated with either left of right scaling.

Implements NOX::Epetra::VectorSpace.

double NOX::Epetra::VectorSpaceScaledL2::norm (  const Epetra_Vector &  a,
NOX::Abstract::Vector::NormType  = NOX::Abstract::Vector::TwoNorm
)  const [virtual]
 

Computes the scaled norm.

Computes the scaled norm using $ Da $ where $D$ is the set of scaling vectors associated with either left of right scaling.

Implements NOX::Epetra::VectorSpace.
