Represents a symbolic matrix factorization (i.e. the pattern of the factors without the values). A single symbolic factorization may be the basis for multiple numerical factorizations of matrices with the same pattern but different nonzero values.
Sparse function to free resources held by these objects. The internal factorization pointer is reference counted, so it is safe to destroy this object even if numeric factorizations exist that still depend on it.
