Detailed Description

Gaussian-type quadrature rule on the real line, including Gauss, Radau, and Lobatto quadrature.

Points and weights are computed to be exact within a tolerance of DOLFIN_EPS. Comparing with known exact values for n <= 3 shows that we obtain full precision (16 digits, error less than 2e-16).
