public final class PolynomialFunctionLagrangeFormTest
extends Object

Test case for Lagrange form of polynomial function.

We use n+1 points to interpolate a polynomial of degree n. This should give us the exact same polynomial as result. Thus we can use a very small tolerance to account only for round-off errors.
