LOBPCGRitzFailure is thrown when the LOBPCG solver is unable to continue a call to LOBPCG::iterate() due to a failure of the algorithm. This signals that the Rayleigh-Ritz analysis over the subspace colsp([X H P]) detected ill-conditioning of the projected mass matrix and the inability to generate a set of orthogonal eigenvectors for the projected problem. This exception is only thrown from the LOBPCG::iterate() routine. After catching this exception, the user can recover the subspace via LOBPCG::getState(). This information can be used to restart the solver. C++ includes: AnasaziLOBPCG.hpp
