Gauss-Lobatto quadrature
 

Hi,

I need weights of 6th order Gauss-Lobatto quadrature points.
The points are given as

x_{i-1/2}, x_{i-sqrt(5)/10}, x_{i+sqrt(5)/10}, x_{i+1/2}
(i : grid points) .

I am trying to find the weights of above points.
But I cannot find.

I would like to know the weights of 6th order Gauss-Lobatto quadrature points, other order Gauss-Lobatto quadrature points and weights.

Thanks.
