Unless I have misunderstood it (which is quite possible!), this problem seems to be a result of an error in the documention for interp3. Adam

In fact the order of the XI,YI,ZI needs to be changed as well. If you change the line ... VI = interp3(X1,Y1,Z1,V,XI,YI,ZI); ... to ... VI = interp3(Y1,X1,Z1,V,YI,XI,ZI); .... then your code should work. Adam |
