Hi,It solved the problem but the function seems to not return valid data, only NaNs.
I tried this: rand('state',0); x = 2*rand(5,1)-1; y = 2*rand(5,1)-1; z = 2*rand(5,1)-1; v = x.^2 + y.^2 + z.^2; d = -0.8:0.05:0.8; [xi,yi,zi] = meshgrid(d,d,d); w = griddata3(x,y,z,v,xi,yi,zi)w only contains NaNs...Is anyone experiencing this problem too? Or am I doing something wrong?
Thanks, António Santos ---

I need to use the griddata3 function, which seems to not be present in these packages. I tried to download de griddata3.m from other distributions but I'm having no success with using this function. griddata3 calls griddata like the following: vi = griddata([x(:),y(:),z(:)],v(:),[xi(:),yi(:),zi(:)],varargin{:}); However, griddata does not accept all these parameters... I also downloaded the source code from Octave 3.0.0 and, althought I didn't test it, it seems that the problem still persists. Any clue on how to use griddata3? Thanks, António SantosOpps, that can't ever have worked as written, but I sure to have tested this... In any case the fact that it doesn't work is my fault, and the attached patch should fix it and adds test code.
