n is continuous and spans your space. It's much harder when your basis functions are piecewise. Ariel Sent by: users-boun...@lists.scilab.org 06/03/2013 10:22 AM Please respond to "International users mailing list for Scilab." To users@lists.scilab.org cc Subject Re:

Re: [Scilab-users] 4D gridding and interpolation of scattered data points

Dear Christophe, Thank you very much for your suggestion. I already had a look at the splin3d functionality, but I believe it will only work for V=f(X,Y,Z) and not for random values of V (i.e. without a pre-defined function of the X, Y and Z coordinates). Kind regards Ariël de Graaf *
