The classes {TYPE}SymRFQREigServer and DComplexHermRFQREigServer are the servers for the root-free QR method of computing eigenvalues. This method computes all the eigenvalues and no eigenvectors.

#include <rw/dseigsrv.h>

main()
{
    DoubleSymMat A;                       // input a matrix
    cin >> A;

    DoubleRFQREigServer server;           // configure a server
    DoubleSymEigDecomp eig = server(A);
}

FloatSymRFQREigServer();
DoubleSymRFQREigServer();
DComplexHermRFQREigServer();

Constructs a server.

RWBoolean
FloatSymRFQREigServer::computeEigenVectors() const;
RWBoolean
DoubleSymRFQREigServer::computeEigenVectors()const;
RWBoolean
DComplexHermRFQREigServer::computeEigenVectors() const;

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