Abstract
The aim of the previous chapters was to show that a polynomial admits a double representation. One is given by its Fourier coefficients with respect to set of orthogonal basis functions, the other by the values at the nodes associated with a suitable high accuracy integration formula. Clearly, it is possible to switch from one representation to the other. The way to do it is the subject of this chapter.
