The classes RWSymQREigServer<T> and RWHermQREigServer<T> are the servers for the QR method of computing eigenvalues. These are the default servers.
#include <iostream> #include <rw/lapack/seigsrv.h> int main() { RWSymMat<double> A; // input a matrix std::cin >> A; RWSymQREigServer<double> server; // configure a

RWSymQREigServer(bool computeVecs=true); RWHermQREigServer(bool computeVecs=true);
Constructs a server. The parameter indicates whether this server should be configured to compute eigenvectors as well as eigenvalues.
void RWSymQREigServer<T>::computeEigenVectors(bool); void RWHermQREigServer<DComplex>::computeEigenVectors (bool);
Sets whether or not the server should compute eigenvectors as well as eigenvalues.
bool RWSymQREigServer<T>::computeEigenVectors() const; bool RWHermQREigServer<DComplex>::computeEigenVectors() const;
Returns true if this server is configured to compute eigenvectors as well as eigenvalues.

(const RWSymTriDiagDecomp<T>& A) const RWSymEigDecomp<double> RWHermQREigServer<DComplex>::decompose
(const RWSymTriDiagDecomp<double>& A) const
Computes the eigenvalue decomposition of the tridiagonal matrix inside the tridiagonal decomposition.
