Module extendr_api::prelude::sparse::utils

Useful sparse matrix primitives.

Functions

• adjoint
  Computes the adjoint of the matrix A and returns a view over it.
• adjoint_symbolic
  Computes the adjoint of the symbolic matrix A and returns a view over it.
• permute_hermitian
  Computes the self-adjoint permutation $P A P^\top$ of the matrix A and returns a view over it.
• permute_hermitian_req
  Computes the size and alignment of the workspace required to compute a two-sided permutation of a self-adjoint matrix.
• sort_dedup_indices
  Sorts and deduplicates row_indices and values simultaneously so that row_indices is nonincreasing and contains no duplicate indices.
• sort_indices
  Sorts row_indices and values simultaneously so that row_indices is nonincreasing.
• transpose
  Computes the transpose of the matrix A and returns a view over it.
