Overview
Sparse
supports the following ordering algorithms:
Default ordering ( | |
User-supplied ordering, or identity if | |
Approximate Minimum Degree (AMD) ordering. Large overhead cost if used for QR-based factorization due to explicit formation of AᵀA. | |
METIS Nested Dissection ordering. Large overhead cost if used for QR-based factorization due to explicit formation of AᵀA. | |
Column AMD ordering for AᵀA. Not valid for symmetric factorizations (use SparseOrderAMD instead). |
