Solver that can compute the least squares solution of an overdetermined linear system.

Required Methods

fn solve_lstsq_in_place(&self, rhs: impl ColBatchMut<E>)

Solves the equation self * X = rhs, in the sense of least squares, and stores the result in the top rows of rhs.

fn solve_lstsq_conj_in_place(&self, rhs: impl ColBatchMut<E>)

Solves the equation conjugate(self) * X = rhs, in the sense of least squares, and stores the result in the top rows of rhs.

fn solve_lstsq<ViewE, B>(&self, rhs: B) -> <B as ColBatch<ViewE>>::Owned

where ViewE: Conjugate<Canonical = E>, B: ColBatch<ViewE>,

Solves the equation self * X = rhs, and returns the result.

fn solve_lstsq_conj<ViewE, B>(&self, rhs: B) -> <B as ColBatch<ViewE>>::Owned

where ViewE: Conjugate<Canonical = E>, B: ColBatch<ViewE>,

Solves the equation conjugate(self) * X = rhs, and returns the result.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
