Hi I am trying to make a gif files from the amount of 500 text files. text files are saved like matrices such as
1.023000000000000000e+03 9.000000000000000000e+00 1.300000000000000000e+01
9.420000000000000000e+02 9.270000000000000000e+02 8.600000000000000000e+01
7.620000000000000000e+02 7.680000000000000000e+02 7.590000000000000000e+02
and I want to make only one gif files included 500 txt files.
Also, I want to make scale bar and automatic range (find minimum and maximum value and set that the minimum and maximum during the play.
Please start at opening the text files!

files = dir('*.txt') ; % get all text files in the folder
N = length(files) ; % total number of files
% gif starts
h = figure;
axis tight manual % this ensures that getframe() returns a consistent size
filename = 'test.gif';
for i = 1:N % loop for each file
% import the file
data = importdata(files(i).name) ;
surf(data) ;
colorbar
drawnow
% Capture the plot as an image
frame = getframe(h);
im = frame2im(frame);
[imind,cm] = rgb2ind(im,256);
% Write to the GIF File
if n == 1
imwrite(imind,cm,filename,'gif', 'Loopcount',inf);
else
imwrite(imind,cm,filename,'gif','WriteMode','append');
end
end

files = dir('*.txt') ;
The above liens reads all test files in the present folder......you need to read about that.
