No, they give indices. You can use those indices in a variety of ways. In my example, I used them to index into vectors which gave the absolute positions of the grid lines. That turned into bricks giving the absolute coordinates for each 3D grid point. > In your example, is there a way to see within your x[ix], y[iy], and z[iz] > matrices the same collection of points that you would see if you did > something like the following? > > points=[] > x=linspace(0,1,3) > y=linspace(1,2.5,4) > z=linspace(3,5,5) > for k in z.tolist(): > for j in y.tolist(): > for i in x.tolist(): > point=array([i,j,k]) > points.append(point) points = column_stack([x[ix].flat, y[iy].flat, z[iz].flat]) -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
