How can I make a shape's color fade more and more over time?

The code below sets each shape to have the same transparency.

hold on; grid on;

axis equal;

scale = .9;

movex = 0;

movey = 0;

squarex = [0 1 1 0];

squarey = [0 0 1 1];

for i = 1:11

    squarex = (squarex * scale + movex);

    squarey = (squarey * scale + movey);

    movex = movex +1;

    movey = movey +1;

    h = fill(squarex,squarey,'r');

    set(h,'facealpha',.7);

pause (.3)

end

Just make a transparency array

transparency = linspace(0, 1, 11); % Make 11 transparencies from 0 to 1 inclusive.

Then

set(h,'facealpha', transparency(i));
