Matlab animation - how to from figures

[Moly]

Compared to the questions out there, my question seems VERY SIMPLE.

I have a code that generates a few graphs. Instead of super-imposing the graphs on one figure, I would like MATLAB to generate an animation of those graphs for me. I tried looking at help and my intution tells me that getframe is the way to go, but my technical capablities do not extend that far.

Any suggestion on how i can animate these figures? Here is my code

x0=0; xt=30; dt=.1;
L=(xt-x0)/dt+1;
n=10;

for k=1:6
t=5*k;
for i=1:L
summ=0;
x(i)=x0+(i-1)*dt;
for j=1:n
npi=j*pi;
a=2*(1-cos(npi))-npi^2*(1+cos(npi));
b= exp((-npi^2*t)/900);
c=sin(npi*x(i)/30);
summ=summ+((a-b)/j^3)*b*c;
end
u(i)=30-x(i)+(60/pi^3)*summ;
end
plot(x,u); hold on
end

xlabel('x')ylabel('u(x,t)')It is possible to animate your graphs using the MATLAB animatedline function. This function allows you to create an animated line plot with a fixed set of data points. You can then control the speed and duration of the animation with the 'FPS' and 'Duration' parameters. In addition, you can also customize the plotting style of your graph, such as colors and markers, through the 'Color' and 'Marker' properties.

To create an animation of your figures in MATLAB, you can use the getframe function as you mentioned. Here are some steps you can follow:

1. First, you will need to create a figure window to display your graphs. You can use the figure() function to do this.

2. Next, you will need to create an axes object within the figure window. You can use the axes() function for this.

3. Within your for loop, after you plot each graph, you can use the getframe() function to capture the current frame of the figure. You can save this frame as a variable, for example "frame".

4. You can then use the movie() function to create an animation from the frames you captured. You can specify the number of frames, frame rate, and other options in this function.

5. Finally, you can play the animation using the movie command. You can also save the animation as a video file using the movie2avi() function.

Here is an example code that you can adapt to your specific case:

x0=0; xt=30; dt=.1; L=(xt-x0)/dt+1; n=10;

% Create figure window and axes object
figure();
ax = axes();

% Define number of frames and frame rate for animation
numFrames = 6;
frameRate = 5;

% Preallocate array to store frames
frames = struct('cdata',[],'colormap',[]);

for k=1:numFrames
t=5*k;
for i=1:L
summ=0;
x(i)=x0+(i-1)*dt;
for j=1:n
npi=j*pi;
a=2*(1-cos(npi))-npi^2*(1+cos(npi));
b= exp((-npi^2*t)/900);
c=sin(npi*x(i)/30);
summ=summ+((a-b)/j^3)*b*c;
end
u(i)=30-x(i)+(60/pi^3)*summ;
end
% Plot graph on axes object
plot(ax,x,u); hold on

% Capture current frame and store it in frames array
frame = getframe(ax);
frames(k) = frame;
end

% Create animation using frames array
movie(frames,1,frameRate);

% Save animation as a video
