How can I make a movie with one multidimensional matrix in MATLAB

Hello, I have a multidimensional matrix in MatLab -> T(41,41,501) and I would like to memorize all this matrix in a movie. What should I do?

I read that the function is VideoWriter but I couldn't make the video. I am attaching the matrix.

cheers.

VidObj = VideoWriter('movie.avi', 'Uncompressed AVI'); %set your file name and video compression
VidObj.FrameRate = 30; %set your frame rate
open(VidObj);
for f = 1:size(T, 3)
    writeVideo(VidObj, T(:, :, f));
end
close(VidObj);

Hey Donald, Look at this.

I add what you send to me at the end of the code. To help you, I will post my code. Cheers

I see. T cannot exceed 1 for double class, and your max value is at 322. To fix this, before my code, normalize T like this:

 T = T / max(T(:))

Perfect Donald, It worked very well. I am adding a new version of the code to show how it is working now. The movie is playing just the last position of the matrix. Why it's happening? Cheers

It's only saving the current figure, and not all figures.

set(gca,'nextplot','replacechildren'); 

for f = 1:size(T,3)
    frame = getframe(gcf);  %Only saving one figure, regardless of frame f
    writeVideo(VidObj,frame);
end
close(VidObj);

Are you plotting T somewhere and then saving a plot of T(:, :, f)? If so, you need to plot inside the for loop. If you want to save T only after normalizing, use this:

T = T / max(T(:));
VidObj = VideoWriter('movie.avi', 'Uncompressed AVI'); %set your file name and video compression
VidObj.FrameRate = 30; %set your frame rate
open(VidObj);
for f = 1:size(T,3)
    writeVideo(VidObj, T(:, :, f));
end
close(VidObj);
