Enum ShiftScale 

pub enum ShiftScale {
    Equilibrated,
    Absolute,
}

Where the static shifts ρ, δ of a Regularization are applied (step K2″ of Algorithm K).

Variants

Equilibrated

On the diagonal of the equilibrated matrix K̃ = S K S (step K2′), whose rows have their largest entry near 1: the shifts are relative to the magnitude of each row, K_reg = K + S⁻¹ Σ S⁻¹. The default.

Absolute

On the diagonal of K itself, in the caller’s units: K_reg = K + Σ.
