如题所述
FILL Filled 2-D polygons.
FILL(X,Y,C) fills the 2-D polygon defined by vectors X and Y
with the color specified by C. The vertices of the polygon
are specified by pairs of components of X and Y. If necessary,
the polygon is closed by connecting the last vertex to the first.%% 示例
t = 0:0.1:2*pi;
r = 4*(1-sin(t));
[x y] = pol2cart(t, r);
fill(x, y, 'r')
