Detailed Description

template<typename T>
class NOX::LAPACK::Matrix< T >

A simple square matrix class for use by NOX::LAPACK::Group.

The matrix is stored as a std::vector<T> array. It is templated so it can store entries of different types. For example, the LOCA LAPACK group stores a complex matrix for Hopf tracking.

Member Function Documentation

numCols()

template<typename T>

int NOX::LAPACK::Matrix< T >::numCols ( ) const

inline

Returns the number of columns in the matrix.

Referenced by LOCA::LAPACK::Interface::computeShiftedMatrix().

numRows()

template<typename T>

int NOX::LAPACK::Matrix< T >::numRows ( ) const

inline

Returns the number of rows in the matrix.

Referenced by NOX::LAPACK::LinearSolver< T >::apply(), LOCA::LAPACK::Group::augmentJacobianForHomotopy(), LOCA::LAPACK::Group::computeComplex(), LOCA::Eigensolver::DGGEVStrategy::computeEigenvalues(), LOCA::LAPACK::Interface::computeShiftedMatrix(), and LOCA::BorderedSolver::LAPACKDirectSolve::setMatrixBlocks().

scale()

template<typename T>

void NOX::LAPACK::Matrix< T >::scale ( T v )

inline

Scale the matrix by a constant value.

This is needed to manipulate matrices in the LOCA library routines.
