I would like to set the colour of each circle according to a given value. (See attached image) The graph must contain this matrix of circles coloured using colourmap.

How do I draw the circles and apply the colourmap to them?

The answer to what is in your question title would be fairly trivial if you actually had the representation of the shapes, but in the body of your question you casually tag on asking how to draw the circles in the first place, which is less easy (or at least not something I am familiar with doing). I would imagine you can parameterise a patch object with the parametric description of a circle, but it's not something I've ever needed to do.

radius = 2;
c_x = 1;
c_y = 1;
numElem = 100;
x = linspace(0,2*pi,numElem);
y = x;
x = radius.*cos(x) + c_x;
y = radius.*sin(y) + c_y;
axis equal
