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=rand(10,1)*10;
y=rand(10,1)*10;
[X Y] = meshgrid(0:1:10,0:1:10);
Z = .......... %must be the number of points in each square grid
meshgrid(X,Y,Z)
How should Z be defined such that it counts the number of values in
each grid of width 1?
