Detailed Description

generate the functionals associated with point set

Given a function space $ E $ and a set of points in the geometric space $\{y_i\}_{i=1...N}$ , generate the set of functionals

$\begin{eqnarray*} \ell_i,j :& E \longrightarrow R, i = 1...N\\ & f \longrightarrow \partial f(y_i)/ \partial x_j \end{eqnarray*}$

associated with the evaluation of the basis functions of the function space at the set of points in the geometric space.
