Details:

I need some kind of help about ezsurf as I understand from my research matlab
fplot is equal to ezplot in octave. And I write a script

fx = @(x,y) x.*sin(y);
fy = @(x,y) -x.*cos(y);
fz = @(x,y) y;
ezsurf(fx, fy, fz,[-5 5 -5 -2],'--','EdgeColor','g')
hold on
ezsurf(fx, fy, fz,[-5 5 -5 -2],'EdgeColor','none')
hold off
if I able to run the script I expect to see the uploaded image(ezsurf).
When I run the script without "'--','EdgeColor','g'" etc it works well, here
is my code and image (ezsurf2)
fx = @(x,y) x.*sin(y);
fy = @(x,y) -x.*cos(y);
fz = @(x,y) y;
ezsurf(fx, fy, fz,[-5 5 -5 -2])
hold on
ezsurf(fx, fy, fz,[-5 5 -5 -2])
hold off

How can I personalize it's color and mini shapes on the graph.
Thank you so much in advance
