Trait ndarray_linalg::least_squares::LeastSquaresSvd

pub trait LeastSquaresSvd<D, E, I> where
    D: Data<Elem = E>,
    E: Scalar + Lapack,
    I: Dimension, {
    fn least_squares(
        &self, 
        rhs: &ArrayBase<D, I>
    ) -> Result<LeastSquaresResult<E, I>>;
}

Solve least squares for immutable references

Required methods

fn least_squares(
    &self,
    rhs: &ArrayBase<D, I>
) -> Result<LeastSquaresResult<E, I>>

Solve a least squares problem of the form Ax = rhs by calling A.least_squares(&rhs). A and rhs are unchanged.

A and rhs must have the same layout, i.e. they must be both either row- or column-major format, otherwise a IncompatibleShape error is raised.

Implementations on Foreign Types

impl<E, D1, D2> LeastSquaresSvd<D2, E, Dim<[usize; 1]>> for ArrayBase<D1, Ix2> where
    E: Scalar + Lapack,
    D1: Data<Elem = E>,
    D2: Data<Elem = E>, 

Solve least squares for immutable references and a single column vector as a right-hand side. E is one of f32, f64, c32, c64. D1, D2 can be any valid representation for ArrayBase (over E).

fn least_squares(
    &self,
    rhs: &ArrayBase<D2, Ix1>
) -> Result<LeastSquaresResult<E, Ix1>>

Solve a least squares problem of the form Ax = rhs by calling A.least_squares(&rhs), where rhs is a single column vector. A and rhs are unchanged.

A and rhs must have the same layout, i.e. they must be both either row- or column-major format, otherwise a IncompatibleShape error is raised.

impl<E, D1, D2> LeastSquaresSvd<D2, E, Dim<[usize; 2]>> for ArrayBase<D1, Ix2> where
    E: Scalar + Lapack,
    D1: Data<Elem = E>,
    D2: Data<Elem = E>, 

Solve least squares for immutable references and matrix (=mulitipe vectors) as a right-hand side. E is one of f32, f64, c32, c64. D1, D2 can be any valid representation for ArrayBase (over E).

fn least_squares(
    &self,
    rhs: &ArrayBase<D2, Ix2>
) -> Result<LeastSquaresResult<E, Ix2>>

Solve a least squares problem of the form Ax = rhs by calling A.least_squares(&rhs), where rhs is matrix. A and rhs are unchanged.

A and rhs must have the same layout, i.e. they must be both either row- or column-major format, otherwise a IncompatibleShape error is raised.
