Thanks for your help Ken. It didn't occur to me to use histogram...
But now I have another question: using histogram (and
reverse_indices) tells me in which bin the x (or y or z) coordinate
would be (and how many x-points are in the bin), but how do I know
where the point (x,y,z) lies? I mean, if my cube goes from 0 to 1, and
I have 4 bins (it could be more) in each dimension (so I would have 64
sub-cubes in 3-D), how can I tell, in a fast way, in which sub-cube
does the point (x,y,z) lies and how many points are in that sub-cube?
Maybe there is an easy answer, but I haven't been able to do it...
Thanks,

Pablo
