Struct QrRef

pub struct QrRef<'a, I, E>
where
    I: Index,
    E: Entity,
{
    symbolic: &'a SymbolicQr<I>,
    indices: &'a [I],
    values: SliceGroup<'a, E>,
}

Sparse QR factorization wrapper.

Fields

symbolic: &'a SymbolicQr<I>

indices: &'a [I]

values: SliceGroup<'a, E>

Implementations

impl<'a, I, E> QrRef<'a, I, E>

where I: Index, E: Entity,

pub unsafe fn new_unchecked( symbolic: &'a SymbolicQr<I>, indices: &'a [I], values: <<E as Entity>::Group as ForType>::FaerOf<&'a [<E as Entity>::Unit]>, ) -> QrRef<'a, I, E>

Creates a QR decomposition reference from its symbolic and numerical components.

Safety:

The indices must be filled by a previous call to SymbolicQr::factorize_numeric_qr with the right parameters.

pub fn symbolic(self) -> &'a SymbolicQr<I>

Returns the symbolic structure of the QR factorization.

pub fn solve_in_place_with_conj( self, conj: Conj, rhs: MatMut<'_, E>, parallelism: Parallelism<'_>, stack: PodStack<'_>, )

where E: ComplexField,

Solves the equation $\text{Op}(A) x = \text{rhs}$ in the sense of least squares, where $\text{Op}$ is either the identity or the conjugate, depending on the value of conj, and stores the result in the upper part of rhs.

work is a temporary workspace with the same dimensions as rhs.

Trait Implementations

fn clone(&self) -> QrRef<'a, I, E>

Formats the value using the given formatter.
