Detailed Description

template<class TypeT>
class RWHermRFQREigServer< TypeT >

The class RWHermRFQREigServer 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/heigsrv.h>

RWHermRFQREigServer<DComplex> server;
RWHermEigDecomp<DComplex> eig = server(A);  // A is a
                                            // RWHermBandMat<DComplex>

Example

#include <iostream>
#include <rw/lapack/heigsrv.h>

int main()
{
    RWHermMat<DComplex> A;                     // input a matrix
    std::cin >> A;

    RWHermRFQREigServer<DComplex> server;      // configure a server
    RWHermEigDecomp<DComplex> eig = server(A);

    return 0;
}

Constructor & Destructor Documentation

template<class TypeT>

RWHermRFQREigServer< TypeT >::RWHermRFQREigServer

(

)

Constructs a server.

Member Function Documentation

template<class TypeT>

virtual bool RWHermRFQREigServer< TypeT >::computeEigenVectors ( ) const

virtual

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

Implements RWHermEigServer< TypeT >.

template<class TypeT>

virtual RWSymEigDecomp<double> RWHermRFQREigServer< TypeT >::decompose ( const RWTriDiagDecomp< TypeT > &  A )

virtual

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

Implements RWHermEigServer< TypeT >.
