Detailed Description

RTROrthoFailure is thrown when an orthogonalization attempt fails.

This is thrown in one of two scenarios. 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 RTROrthoFailure exception.
