Eval Split eq eval

ArkLib.Lattices.Hachi.evalSplit_eq_eval

Plain-language statement

The split. Evaluating a multilinear polynomial equals the vector–matrix–vector product of its reshaped coefficient matrix with the monomial bases of the low and high evaluation points (Hachi [NOZ26, §4]).

Plain-language statement

The split (Lagrange representation). Evaluating a multilinear polynomial given by its hypercube values equals the vector–matrix–vector product of its reshaped value matrix with the Lagrange bases of the low and high evaluation points.
