Could someone tell me how to obtain a legend for (filled) contour
plots using MATLAB. Thanks.

Does 'colorbar' do what you want?

This is what I am doing: from a grid-based computation data (in my
case, FEM), I use patch to plot ``patch graphics" and then use
interpolated shading. Is there someway to make MATLAB show the levels
(of the field values) to which the colors (from shading) correspond?
Is there also a way to control the number of levels in the
interpolated shading?

From the documentation:
"colormap(hsv(128)) creates an hsv colormap with 128 colors. If you do
not specify a size, MATLAB creates a colormap the same size as the
current colormap."

This assumes equal spacing of you colour-value mapping.
