Detailed Description

template<class TypeT>
class RWHermRFQREigServer< TypeT >

The class RWHermRFQREigServer<T> 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>

Examples

 #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;
 }

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 >.
