|LOBPCGOrthoFailure (const std::string &what_arg)|
This is thrown in one of two scenarstd::ios. After preconditioning the residual, the orthogonalization manager is asked to orthogonalize the preconditioned residual (H) against the auxiliary vectors. If full orthogonalization is enabled, H is also orthogonalized against X and P and normalized.
The second scenario involves the generation of new X and P from the basis [X H P]. When full orthogonalization is enabled, an attempt is made to select coefficients for X and P so that they will be mutually orthogonal and orthonormal.
If either of these attempts fail, the solver throws an LOBPCGOrthoFailure exception.
