Detailed Description

RTRRitzFailure is thrown when the RTR solver is unable to continue a call to RTRBase::iterate() due to a failure of the algorithm.

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.
