Struct StandardizedCeiling 

pub struct StandardizedCeiling { /* private fields */ }

One affine wall, already expressed in the cubature’s own standardized coordinates.

The box ceiling the cubature already carries is a wall whose normal is a single coordinate, so it constrains that coordinate directly. A general wall aᵀu ≤ c does not: after u = mean + L z it reads (Lᵀa)ᵀz ≤ c − aᵀmean, which constrains the LAST coordinate its transformed normal touches, given the ones drawn before it. That is the whole difference between the two, and it is why the limit has to be computed per node rather than once per coordinate.

pivot is that last touched coordinate. The wall says nothing about any coordinate before it and must not be consulted there.

Implementations

impl StandardizedCeiling

pub fn new( normal: &Array1<f64>, bound: f64, mean: &Array1<f64>, factor: ArrayView2<'_, f64>, ) -> Result<Self, String>

Build the standardized form of normal · u ≤ bound for the law u ~ N(mean, L Lᵀ).

Refuses a wall whose transformed normal vanishes: such a wall constrains no coordinate of the cubature and is either redundant or infeasible, and the two cannot be told apart from the normal alone.
