Lagrange returns the Lagrange coefficients at 0 for all parties in the interpolation domain.

LagrangeFor returns the Lagrange coefficients at 0 for all parties in the given subset.

LagrangeSingle returns the lagrange coefficient at 0 of the party with index j.

NewPolynomial generates a Polynomial f(X) = secret + a₁⋅X + … + aₜ⋅Xᵗ, with coefficients in ℤₚ, and degree t.

NewPolynomialExponent generates an Exponent polynomial F(X) = [secret + a₁•X + … + aₜ•Xᵗ]•G, with coefficients in 𝔾, and degree t.

Sum creates a new Polynomial in the Exponent, by summing a slice of existing ones.

Exponent represent a polynomial F(X) whose coefficients belong to a group 𝔾.

Polynomial represents f(X) = a₀ + a₁⋅X + … + aₜ⋅Xᵗ.
