Implementations§

§

impl<I> SymbolicSupernodalCholesky<I>
where I: Index,

pub fn n_supernodes(&self) -> usize

Returns the number of supernodes in the Cholesky factor.

pub fn nrows(&self) -> usize

Returns the number of rows of the Cholesky factor.

pub fn ncols(&self) -> usize

Returns the number of columns of the Cholesky factor.

pub fn len_values(&self) -> usize

Returns the length of the slice that can be used to contain the numerical values of the Cholesky factor.

pub fn supernode_begin(&self) -> &[I]

Returns a slice of length self.n_supernodes() containing the beginning index of each supernode.

pub fn supernode_end(&self) -> &[I]

Returns a slice of length self.n_supernodes() containing the past-the-end index of each

pub fn col_ptrs_for_row_indices(&self) -> &[I]

Returns the column pointers for row indices of each supernode.

pub fn col_ptrs_for_values(&self) -> &[I]

Returns the column pointers for numerical values of each supernode.

pub fn row_indices(&self) -> &[I]

Returns the row indices of the Cholesky factor.

§Note

Note that the row indices of each supernode do not contain those of the block diagonal part.

pub fn supernode(&self, s: usize) -> SymbolicSupernodeRef<'_, I>

Returns the symbolic structure of the s’th supernode.

pub fn solve_in_place_req<E>( &self, rhs_ncols: usize, ) -> Result<StackReq, SizeOverflow>
where E: Entity,

Returns the size and alignment of the workspace required to solve the system A×x = rhs.
