[−][src]Trait ndarray_linalg::least_squares::LeastSquaresSvdInPlace

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

Solve least squares for mutable references, overwriting the input fields in the process

Required methods

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

Solve a least squares problem of the form Ax = rhs by calling A.least_squares(&mut rhs), overwriting both A and rhs. This uses the memory location of A and rhs, which avoids some extra memory allocations.

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, D> LeastSquaresSvdInPlace<D, E, Dim<[usize; 1]>> for ArrayBase<D, Ix2> where
    E: Scalar + Lapack + LeastSquaresSvdDivideConquer_,
    D: DataMut<Elem = E>, [src]

Solve least squares for mutable references and a vector as a right-hand side. Both values are overwritten in the call.

E is one of f32, f64, c32, c64. D can be any valid representation for ArrayBase.

fn least_squares_in_place(
    &mut self,
    rhs: &mut ArrayBase<D, Ix1>
) -> Result<LeastSquaresResult<E, Ix1>>[src]

Solve a least squares problem of the form Ax = rhs by calling A.least_squares(rhs), where rhs is a vector. A and rhs are overwritten in the call.

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, D> LeastSquaresSvdInPlace<D, E, Dim<[usize; 2]>> for ArrayBase<D, Ix2> where
    E: Scalar + Lapack + LeastSquaresSvdDivideConquer_,
    D: DataMut<Elem = E>, [src]

Solve least squares for mutable references and a matrix as a right-hand side. Both values are overwritten in the call.

E is one of f32, f64, c32, c64. D can be any valid representation for ArrayBase.

fn least_squares_in_place(
    &mut self,
    rhs: &mut ArrayBase<D, Ix2>
) -> Result<LeastSquaresResult<E, Ix2>>[src]

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

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.
