NonFiniteMatrixEntry

At least one matrix entry is not finite.

NonFiniteVectorEntry

At least one vector entry is not finite.

NonFiniteTolerance

A solver tolerance is not finite.

NegativeTolerance

A solver tolerance is negative.

EmptyCandidateDirections

No candidate projection directions were supplied.

NonSymmetricSystemMatrix

The system matrix is not symmetric within numerical tolerance.

SystemMatrixNotPositiveDefinite

The system matrix is not positive definite.

NonSymmetricCovariance

The covariance matrix is not symmetric within numerical tolerance.

CovarianceNotPositiveSemidefinite
