Module amd

Approximate minimum degree ordering.

Structs

• Control
  Tuning parameters for the AMD implementation.
• FlopCount
  Flop count of the LDLT and LU factorizations if the provided ordering is used.

Functions

• order
  Computes the approximate minimum degree ordering for reducing the fill-in during the sparse Cholesky factorization of a matrix with the sparsity pattern of A + A.T.
• order_maybe_unsorted
  Computes the approximate minimum degree ordering for reducing the fill-in during the sparse Cholesky factorization of a matrix with the sparsity pattern of A + A.T.
• order_maybe_unsorted_req
  Computes the size and alignment of required workspace for computing the AMD ordering of an unsorted matrix.
• order_req
  Computes the size and alignment of required workspace for computing the AMD ordering of a sorted matrix.
