Detailed Description

template<class ScalarType, class MV, class OP>
class Anasazi::MatOrthoManager< ScalarType, MV, OP >

Anasazi's templated virtual class for providing routines for orthogonalization and orthonormalization of multivectors using matrix-based inner products.

This class extends Anasazi::OrthoManager by providing extra calling arguments to orthogonalization routines, to reduce the cost of applying the inner product in cases where the user already has the image of target multivectors under the inner product matrix.

A concrete implementation of this class is necessary. The user can create their own implementation if those supplied are not suitable for their needs.

template<class ScalarType , class MV , class OP >

int Anasazi::MatOrthoManager< ScalarType, MV, OP >::getOpCounter ( ) const

Retrieve operator counter.

This counter returns the number of applications of the operator specifying the inner product. When the operator is applied to a multivector, the counter is incremented by the number of vectors in the multivector. If the operator is not specified, the counter is never incremented.
