Many year ago i had posted :
https://fr.mathworks.com/matlabcentral/fileexchange/6132-n-d-customized-gridding
and
https://fr.mathworks.com/matlabcentral/fileexchange/6133-fast-indexed-color-voxel
This is a full and self-contained fonctionnal example (random data) demonstrate how to draw density map using these (actually old) tools on random data. ENJOY ;-)
Launch testgrid.m to start. All 'm files' have to be placed in the same directory.
Works on Matlab 2018b and previous (not tested on most recent realeases yet)
