Detailed Description

Anasazi operator for computing eigenvalues of the inverse-Jacobian.

This class implements the LOCA::AnasaziOperator::AbstractStrategy interface for computing eigenvalues of the inverse-Jacobian.


Member Function Documentation

void LOCA::AnasaziOperator::JacobianInverse::apply ( const NOX::Abstract::MultiVector input,
NOX::Abstract::MultiVector output 
) const [virtual]

Apply the operator.

Computes $\mbox{output} = J^{-1}\mbox{input}$.

Implements LOCA::AnasaziOperator::AbstractStrategy.

NOX::Abstract::Group::ReturnType LOCA::AnasaziOperator::JacobianInverse::rayleighQuotient ( NOX::Abstract::Vector evec_r,
NOX::Abstract::Vector evec_i,
double &  rq_r,
double &  rq_i 
) const [virtual]

Compute Rayleigh quotient.

Computes the Rayleigh quotient $z^T J z$ for the eigenvector $z$.

Implements LOCA::AnasaziOperator::AbstractStrategy.

void LOCA::AnasaziOperator::JacobianInverse::transformEigenvalue ( double &  ev_r,
double &  ev_i 
) const [virtual]

Transform eigenvalue.

Transforms the given eigenvalue to the eigenvalue of the Jacobian by inverting it.

Implements LOCA::AnasaziOperator::AbstractStrategy.
