I am using 'fill' function to plot my result. Can I use transparent
color to plot my result?

Thanks!

Use the FaceAlpha property:

close all
t = (1/16:1/8:1)'*2*pi;
x = sin(t);
y = cos(t);
fill(x,y,'r','facealpha',.5)
axis square

% Now plot a sphere beneath to show the transparency.
hold on
[x y z]=sphere;
surf(x/2,y/2,z/2-1)
