Expand description

UDU factorization.

Fields

u: Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>

The upper triangular matrix resulting from the factorization

d: Matrix<T, D, Const<1_usize>, <DefaultAllocator as Allocator<T, D, Const<1_usize>>>::Buffer>

The diagonal matrix resulting from the factorization

Implementations

impl<T, D> UDU<T, D> where
    T: RealField,
    D: Dim,
    DefaultAllocator: Allocator<T, D, Const<1_usize>>,
    DefaultAllocator: Allocator<T, D, D>,

pub fn new(
p: Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>
) -> Option<UDU<T, D>>

Computes the UDU^T factorization.

The input matrix p is assumed to be symmetric and this decomposition will only read the upper-triangular part of p.

pub fn d_matrix(
&self
