Can I speed up this iterative ploting?

Hello.

I need to plot a graph iteratively. (about 10000 times)

One plot consists of a number of sub-plotting as follows.

figure(1)
hold on

u_deformed = rand(54, 24);
 w_deformed = rand(54, 24);

    for i = 1:size(u_deformed, 1)
          plot(u_deformed(i, :), w_deformed(i, :),'b','linewidth', 8)
    end

Here, the size of the matrix [u_deformed] and [w_deformed] are 54X24, respectively.

This plot is for drawing a deformed shape of a structure at a certain time step. For each time step, the matrix [u_deformed] and [w_deformed] are changed.

It takes about 0.04 sec for one set of plotting. But, the problem is I need to do it for about 10000 times.

It means it would take 0.04*10000 sec. This is quite problematic for me.

I tried to use parfor for this plotting. But it made the speed even slower.

I want to know whether there is a way for plotting whole this data without for-loop statement.

What is wrong when you reduce the iteration?

Why you are going for plot when you have a matrix? YOu should use surf eh.

You should try using set. Check the below pseudo code:

h = plot(rand(10,1)) ;
for i = 1:10
    set(h,'YData',rand(10,1))
    pause(0.1)
end

Thank you. 'set' is much faster than re-plot.
