Detailed Description

Radau (Gauss-Radau) quadrature on the interval [-1,1]. The n quadrature points are given by the zeros of

( Pn-1(x) + Pn(x) ) / (1+x)

where Pn is the n:th Legendre polynomial.

The quadrature points are computed using Newton's method, and the quadrature weights are computed by solving a linear system determined by the condition that Radau quadrature with n points should be exact for polynomials of degree 2n-2.
