Dear all,

I would like to plot some 3D color-coded density plots, using
meshgrid. I have this grid on a 2D surface (generated with meshgrid).
Now, I am absolute stuck when it comes to counting the number of
points falling in each grid --- I would like to use that number as
some kind of a density per grid, which constitutes the 3rd dimension.
Here I have a little demonstration:

clear, clc, clf;
[X Y] = meshgrid(0:1:10,0:1:10);
Z =   .......... %must be the number of points in each square grid

How should Z be defined such that it counts the number of values in
each grid of width 1?
