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.

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
