Exception Summary
NotFullRankException This is the exception produced by a Triangular method if a matrix has at least one zero diagonal element.
NotPosDefException This is the exception produced by the Cholesky factorization if it determines that the matrix to be factored is not positive definite.
SVDCException This is the exception produced by the Singular Value Decomposition method.
