I'm having my code here where I want to put animation. Can we show this animation wrt to any parameter?

To create an animation you will need to plot continuously different plots. Say you want to have 10 or 20 frames in your animation you could do this with a for loop:
for k=1:10
% use your code here, change the variables and surf each time
end
Now, you will need to grab each plot, so after each surf add the following:
drawnow
F(k) = getframe;
The variable F will contain your animation and then you can save as a video like this
v = VideoWriter('video_name'), 'MPEG-4');
open(v);
writeVideo(v,F);
close(v);
Hope this helps. If this does not solve your problem, please let me know. If it does, please accept the answer.

See this example using variable 't'. Adapt it according to your requirement
%suface plot;
x=-20:1:20;
y=-20:1:20;
[x,y]=meshgrid(x,y);
c1=0.1576;
A1=0.9706;
A2=0.9572;
A3=0.4854;
A4=2*A3;
T = linspace(0, 1, 100);
fig = figure;
ax = axes();
hold(ax);
view(3);
grid on
colormap jet;
xlabel('\bf{x}','fontsize',18);
ylabel('\bf{y}','fontsize',18);
zlabel('\bf{u (x,y,t)}','fontsize',18);
s = surf(x,y,zeros(size(x)),'Facealpha','1'); % temporary surface to get the handle
v = VideoWriter('test.mp4', 'MPEG-4');
open(v);
for i=1:numel(T)
t=T(i);
b=cos(t);
A=log(b);
s.ZData = c1./((x./(A1+3*t).^1./3+A-(A2+y)./(A1+3*t).^1./3-A4)*(A1+3*t).^1./3);
drawnow;
frame = getframe(fig);
writeVideo(v, frame)
end
close(v);

You want to add images to pdf file? See export graphics() to save images at few values of 'y'.
