I would like your help. I am newbie in MATLAB. In my program I calculate 2D plot profiles as the attached pic.
on this Y-X 2D plot, the Y array being calculated for 10 time steps. I would like to make a surface evolution of all this plots around x=0; at least for the last one. Eventually to create a surface 3Dplot, like a half sphere. The Z axis could be the same as X axis; so the radius to be from 0 to 1 according the attached pic. Please, can someone help me on this? Any idea is more than welcome. thank you.

Konstantinos, try this one:
R = 0:0.1:1;
z = cos(-R); % that'd be your current y-function
th = 0:pi/20:2*pi;
X = bsxfun(@times,R',cos(th));
Y = bsxfun(@times,R',sin(th));
Z = repmat(z',1,length(th));
surf(X,Y,Z)

Yep, see updated code above.
set(gca,'zlim',[0 1],'ylim',[-5 5]) % keep limits on z and y axis
Does this answer your questions?

Yes! I did not try the above answer yet, cause I have two parts on my code. Thank you!!!
