orld.wolfram.com/Legendre-GaussQuadrature.html"> Legendre-Gauss quadrature. Because of its
non-adaptive nature, this algorithm can converge to a wrong value for the integral (for example, if the function is significantly different from zero toward the ends of the integration interval). In particular, a change of variables aimed at estimating integrals over infinite intervals as proposed
here should be avoided when using this class.
