Hello all, If I have a set of points (xi,yi} where i=1 to n and I want to find a best fit curve (say mth order polynomial) that describes these data points, I could use the following commands. data = {{x1,y1},{x2,y2},...,{xn,yn}} Fit[data,{1,x,x^2,...,x^m},s]] Now I have a set of 3D points {xi,yi,zi} and I want to plot the surface describe by these points and to find the equation that describe this surface. Is there a similar way to do what I have described above for 2D? Thanks in advance, John Lai
