Struct ScaledChunkedPolynomial 

Source 
struct ScaledChunkedPolynomial<F, P>(Vec<(F, P)>);
Expand description

A formal sum of the form s_0 * p_0 + ... s_n * p_n where each s_i is a scalar and each p_i is a polynomial. The parameter P is expected to be the coefficients of the polynomial p_i, even though we could treat it as the evaluations.

This hypothesis is important if to_dense_polynomial is called.

Implementations§

Source§

impl<F, P> ScaledChunkedPolynomial<F, P>

Source

fn add_poly(&mut self, scale: F, p: P)

Source§

impl<F: Field> ScaledChunkedPolynomial<F, &[F]>

Source

fn to_dense_polynomial(&self) -> DensePolynomial<F>

Compute the resulting scaled polynomial. Example: Given the two polynomials 1 + 2X and 3 + 4X, and the scaling factors 2 and 3, the result is the polynomial 11 + 16X.

2 * [1, 2] + 3 * [3, 4] = [2, 4] + [9, 12] = [11, 16]
