	Evaluate polynomials at x.

Detailed Description

template<std::floating_point T, std::size_t max_order, bool use_table = false>
class Faunus::Legendre< T, max_order, use_table >

Evaluate n'th degree Legendre polynomial.

Example:

Legendre<float, 10> l;
auto P = l.eval(1.3)
std::cout << P[3]; --> third order value

Note

Since C++17 there's std::legendre but this seems more efficient if a range of degrees are needed

Template Parameters

T	floating point type (double, float, ...)
max_order	Maximum order to evaluate
use_table	Use lookup table for 1+1/i? Default = false

Todo:

Benchmark use_table
