Animation help needed
I'm trying to display 10 graphs in a sequence as an animation, running from t=1 to t=10. Here's my code,
close all;
clear all;
l=0.33;R=100;T=68;m=0.000125;w0=0.1;t=0;mu=m/l;c=sqrt(T/mu);r=1/2;x0=l*r;
for t = 1:10
for x=1:34;
for n=1:5000;
wxt=((4*w0)/pi)*exp(-R*(t*0.001))*((l/(pi*n^2*x0))...
*sin((n*pi*x0)/l))*sin((n*pi*((x-1)*0.01))/l)*cos((sqrt((c*n*pi/l)^2-R^2)*(t*0.001)));
wxtrec(n)=wxt;
end
w=sum(wxtrec);
wrec(x)=w;
end
end
plot(1:34,wrec(t+10))
axis equal
M(t) = getframe
%plot(1:34,wrec)
The bottom plot works by its self, displaying the graph of t=10, but I can't seem to make the animation work.
Any help would be really appreciated.

Hi,
You can write :
axis ([0 35 -0.05 0.05]);
before line
plot(1:34,wrec)
inside the loop.
Or you can also set the axis unvisible inside the loop by
axis off

If you're not actually trying to make a movie, just visualize the animation within MATLAB, I'd highly recommend calling "plot" just once and capturing a handle to the plot object. You can then update this handle's "ydata" property within your loop without repeatedly calling plot. The result is that the animation will be much smoother and you'll be able to zoom, pan, rotate interactively during the animation without everything reseting. Here is a simple example - try rotating, etc. mid animation to see what Im talking about:
x = -1:0.01:1;
y = x.^2;
h = plot(x,y);
axis([-1,1,-1,1]);
for t = 1:500
set(h,'ydata',cos(t/10)*y);
pause(0.1);
end
Good luck!
