The classes RWSymRFQREigServer<T> and RWHermRFQREigServer<T> are the servers for the root-free QR method of computing eigenvalues. This method computes all the eigenvalues and no eigenvectors.

#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;
}

RWSymRFQREigServer();
RWHermRFQREigServer();

Constructs a server.

                                             const;

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