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

computeEigenVectors()

template<class TypeT >

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

virtual

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

Implements RWHermEigServer< TypeT >.

decompose()

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 >.
