Expand description
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>)
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>)
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
fn solve_lstsq<ViewE, B>(&self, rhs: B) -> <B as ColBatch<ViewE>>::Owned
Solves the equation self * X = rhs
, and returns the result.
fn solve_lstsq_conj<ViewE, B>(&self, rhs: B) -> <B as ColBatch<ViewE>>::Owned
fn solve_lstsq_conj<ViewE, B>(&self, rhs: B) -> <B as ColBatch<ViewE>>::Owned
Solves the equation conjugate(self) * X = rhs
, and returns the result.
