Detailed Description

Lobatto (Gauss-Lobatto) quadrature on the interval [-1,1]. The n quadrature points are given by the end-points -1 and 1, and the zeros of P{n-1}'(x), where P{n-1}(x) is the (n-1):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 Lobatto quadrature with n points should be exact for polynomials of degree 2n-3.
