Trait Implementations

impl<L: LinAlg> Cone<L> for ConeZero<L>

fn proj(&mut self, dual_cone: bool, x: &mut L::Sl) -> Result<(), ()>

Calculates \(\Pi_\mathcal{K}(x)\), that is euclidean projection of \(x\) onto the cone \(\mathcal{K}\).

fn product_group<G: Fn(&mut L::Sl) + Copy>(&self, _dp_tau: &mut L::Sl, _group: G)

Performs grouping for a diagonal preconditioning vector according to the cone \(\mathcal{K}\).
