Detailed Description

template<class TypeT>
class RWSymRFQREigServer< TypeT >

The class RWSymRFQREigServer is the server for the root-free QR method of computing eigenvalues. This method computes all the eigenvalues and no eigenvectors.

Synopsis
#include <rw/lapack/seigsrv.h>
RWSymEigDecomp<double> eig = server(A); // A is a RWSymBandMat<double>
Example
#include <iostream>
#include <rw/lapack/seigsrv.h>
int main()
{
RWSymMat<double> A; // input a matrix
std::cin >> A;
RWSymRFQREigServer<double> server; // configure a server
RWSymEigDecomp<double> eig = server(A);
return 0;
}

Constructor & Destructor Documentation

template<class TypeT>
RWSymRFQREigServer< TypeT >::RWSymRFQREigServer ( )

Constructs a server.

Member Function Documentation

template<class TypeT>
virtual bool RWSymRFQREigServer< TypeT >::computeEigenVectors ( ) const
virtual

Always returns false, since this server can not compute eigenvectors.

Implements RWSymEigServer< TypeT >.

template<class TypeT>
virtual RWSymEigDecomp<TypeT> RWSymRFQREigServer< TypeT >::decompose ( const RWTriDiagDecomp< TypeT > &  A)
virtual

Computes the eigenvalue decomposition of the tridiagonal matrix inside the tridiagonal decomposition.

Implements RWSymEigServer< TypeT >.
