Struct nalgebra::linalg::UDU[−][src]

pub struct UDU<T: RealField, D: Dim> where
    DefaultAllocator: Allocator<T, D> + Allocator<T, D, D>,  {
    pub u: OMatrix<T, D, D>,
    pub d: OVector<T, D>,
}
Expand description

UDU factorization.

Fields

u: OMatrix<T, D, D>

The upper triangular matrix resulting from the factorization

d: OVector<T, D>

The diagonal matrix resulting from the factorization

Implementations

impl<T: RealField, D: Dim> UDU<T, D> where
    DefaultAllocator: Allocator<T, D> + Allocator<T, D, D>, [src]

pub fn new(p: OMatrix<T, D, D>) -> Option<Self>[src]

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.
