Dear All, given a set of points in list={y1,y2,...,yk} one can use f=Interpolation[list] to get an implicit interpolation function which can be plotted etc., but I did not find out how to get the explicit polynomial f[x] which is implicitely generated and used by calling f[x] (i.e. the coefficients of the powers in 'x') in order to port this algebraic expression into a C code for further use. Any ideas welcome (preferably e-mail), Thanks in advance Manfred Krafczyk ==== [MESSAGE SEPARATOR] ====
