Detailed Description

Gauss Lobatto quadrature rule including both endpoints.

is exact for and n = p+1 points. n must be greater or equal to 2.

The abscissas are the zeros of and the weights are .

The computations and the storage of the values are done by the class Quadrature with template parameter 0. The difference between this class and Quadrature is that it is in a class hierarchy of quadrature rules. This has advantages when dynamically switching quadrature rules is needed. On the other hand, this class returns the values via a virtual function call abscissas() and weights() should therefore not be called to often (inside loops etc.).
