Structure

SparseSymbolicFactorOptions

A structure that contains options that affect the symbolic stage of a sparse factorization.

Declaration

typedef struct {
    ...
} SparseSymbolicFactorOptions;

SparseSymbolicFactorOptions supports the following ordering algorithms:

`SparseOrderDefault`	Default ordering (`SparseOrderAMD` for symmetric and `SparseOrderCOLAMD` for unsymmetric factorizations, but this may change in the future).
`SparseOrderUser`	User-supplied ordering, or identity if `order` is null.
`SparseOrderAMD`	Approximate Minimum Degree (AMD) ordering. Large overhead cost if used for QR-based factorization due to explicit formation of AᵀA.
`SparseOrderMetis`	METIS Nested Dissection ordering. Large overhead cost if used for QR-based factorization due to explicit formation of AᵀA.
`SparseOrderCOLAMD`	Column AMD ordering for AᵀA. Not valid for symmetric factorizations (use SparseOrderAMD instead).
