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