Plotting matrices on a Raster

[Fabio Mascelloni]

I'd like to plot on a raster a n*n matrix (currently 10*10) of float values
in the range [0.0 1.0], each value corrisponding to a color, from black of
0.0 to red of 1.0, through all the possibles values.This was already made
using Matlab
(look at the attached pic) and I'd like to obtain a similar effect with
SWARM.
I've tried using Diffuse2D, for example, but without good results. I'm
wondering if it's possible.
Fabio.
