5. Implementing discretization
We will give the expression of the Lagrange polynomials and their derivatives to construct the first and second derivation matrices. We'll need them to write the algebraic system to be inverted to solve, for example, the equation (18).
5.1 Die assembly
For , we denote by hi the Lagrange polynomial characteristic of the i-th Gauss-Lobatto point: this polynomial verifies hi(ξj) = δij,...
