According to the "help fill"
If C is a vector or matrix then the color data is first
scaled using 'caxis' and then indexed into the current colormap. A
row vector will color each polygon (a column from matrices X and Y)
with a single computed color. A matrix C of the same size as X and
Y will compute the color of each vertex and then interpolate the
face color between the vertices.
this becomes ambiguous if size of each X, Y, and C is 3 because
C could also be an RGB triad ([ r g b]).
Dmitri.
