Module extendr_api::prelude::sparse::linalg::lu::simplicial

Simplicial factorization module.

A supernodal factorization is one that processes the elements of the LU factors of the input matrix by single elements, rather than by blocks. This is more efficient if the LU factors are very sparse.

Structs

• SimplicialLu
  LU factor structure containing the symbolic and numerical representations.

Functions

• factorize_simplicial_numeric_lu
  Computes the numeric values of the LU factors of the matrix A as well as the row pivoting permutation, and stores them in lu and row_perm/row_perm_inv.
• factorize_simplicial_numeric_lu_req
  Computes the size and alignment of the workspace required to perform a numeric LU factorization.
