I am using isosurface to plot 3d density maps. I would like to plot multiple maps in the same figure, each one with a different color. How can I do so?

You can try this:
[x,y,z,v] = flow;
figure;
p = patch(isosurface(x,y,z,v,-3));
p.FaceColor = 'yellow';
hold on;
p = patch(isosurface(x*3,y*1,z*3,v,-3));
p.FaceColor = 'red';
p.EdgeColor = 'none';
p = patch(isosurface(x*1,y*3,z*3,v,-3));
p.FaceColor = 'green';
p.EdgeColor = 'none';
hold off;

Hi Guy, Please provide a sample for A matrix too. The code doesn't run without it.
