I have used the rectangle function to generate a geometric object with a specified fill color using rgb [ x y z].
How can I generate a legend entry for my object?
I have thought of generating a random point of the same color within the boundaries of my object, but wanted to know if there was a more obvious solution?

You can use the handle to the patch object that fill returns.
h=fill([1 1 0 0],[0 1 1 0],'r');
axis([-0.5 1.5 -0.5 1.5])
legend(h,'red square')
