|RTRRitzFailure (const std::string &what_arg)|
This signals that the Rayleigh-Ritz analysis of
X + Eta detected ill-conditioning of the projected mass matrix and the inability to generate a set of orthogonal eigenvectors for the projected problem (if thrown from iterate()) or that the analysis of the initial iterate failed in RTRBase::initialize().
After catching this exception, the user can recover the subspace via RTRBase::getState(). This information can be used to restart the solver.
