Implementations§
§impl<E> PartialPivLu<E>where
E: ComplexField,
impl<E> PartialPivLu<E>where
E: ComplexField,
pub fn new<ViewE>(matrix: MatRef<'_, ViewE>) -> PartialPivLu<E>where
ViewE: Conjugate<Canonical = E>,
pub fn new<ViewE>(matrix: MatRef<'_, ViewE>) -> PartialPivLu<E>where
ViewE: Conjugate<Canonical = E>,
Returns the LU decomposition of the input matrix with partial (row) pivoting.
The factorization is such that $PA = LU$, where $L$ is lower triangular, $U$ is unit upper triangular, and $P$ is the permutation arising from the pivoting.
pub fn row_permutation(&self) -> PermRef<'_, usize>
pub fn row_permutation(&self) -> PermRef<'_, usize>
Returns the row permutation due to pivoting.
pub fn transposition_count(&self) -> usize
pub fn transposition_count(&self) -> usize
Returns the number of transpositions that constitute the permutation.
