Using fill to color multiple polygons using input RGB color values.

Greetings:

I have a problem using "fill" to produce two polygons, each with a color defind by rgb values. The following code defines two matrices, xx and yy, with columns representing the vertices of the two polygons. A 3D matix c, contains the rgb values of the colors.

Using "fill" in the form : fill(x1,y1,c1,x2,y2,c2, ...) to color each polygon, works fine. But using it in the manner fill(xx,yy,c) doesn't produce the correct colors. So, how to fix that to use it in the latter way?

xx = [0 0 1 1 0; 1 1 2 2 1]';
yy = [0 1 1 0 0; 0 1 1 0 0]';
c(1,1,:) = [0.6 0.6 0.8];
c(2,1,:) = [0.3 0.3 0.4];
figure;fill(xx,yy,c);
figure;fill(xx(:,1),yy(:,1),c(1,1,:),xx(:,2),yy(:,2),c(2,1,:));

The output figures of the code are here:

Try this

[x,y] = meshgrid(0:2,0:1);
c1(1,1,:) = [0.6 0.6 0.8];
c2(1,1,:) = [0.3 0.3 0.4];
c  = [c1 c2 c2;c1 c2 c2];
surf(x,y,x*0,c)
view(0,90)
