SparseOpaqueSymbolicFactorization

Declaration

struct SparseOpaqueSymbolicFactorization

Overview

Represents a symbolic matrix factorization (that is, 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.

Use the SparseCleanup(_:) function to free resources that these objects hold. The system reference-counts the internal factorize pointer, so it’s safe to destroy this object even if numeric factorizations exist that still depend on it.
