Trait Preconditioner 

pub trait Preconditioner<T>: Send + Sync
where
    T: ComplexField,
{
    // Required method
    fn apply(
        &self,
        r: &ArrayBase<OwnedRepr<T>, Dim<[usize; 1]>>,
    ) -> ArrayBase<OwnedRepr<T>, Dim<[usize; 1]>>;
}

Trait for preconditioners used in iterative solvers.

A preconditioner M approximates A^(-1), so that M*A is better conditioned than A alone. This accelerates convergence of iterative methods.

Required Methods

fn apply( &self, r: &ArrayBase<OwnedRepr<T>, Dim<[usize; 1]>>, ) -> ArrayBase<OwnedRepr<T>, Dim<[usize; 1]>>

Apply the preconditioner: y = M * r

This should approximate solving A * y = r
