I have following code:
A=load('CurRunA.dat');
X=A(:,1); Y=A(:,3);
figure( plot(X,Y)
I want to run this code for several files CurRunA, CurRunB, CurRunC..... How can I run this code automatically for all the files like these and plot the X,Y curve for all those data in a single plot with different colors?
I can rename those files for the sake of programing. Also, if I have 20 files and if I want to do this only up to 10 files, how can I stop the program till 10 and provide the output?

PATH = 'C:\myFilesAreHere\'; %remember the last \
files=dir([PATH,'*.dat']) ; %get info about all files in PATH that ends with .dat
fileNames={files.name}; %extract only filenames, put them in a cell.
%im not sure if the filenames are allredy sorted or not but to be sure:
fileNames=sort(fileNames);
nFiles=numel(fileNames); %count number of files
colorMap={'red','blue','green',... etc} % if your run out of colors use e.g '-.red'
for i=1:min(nFiles,10) %run for either 1:10 or 1:nFiles if nFiles<10.
A=load([PATH,'fileNames{i}']);
% your code
figure;plot(X,Y,colorMap{i} );
end
%%%%%%% END %%%%%
This ok? =)

Yes, thank you. I put fileNames=(files.name)! OK. But now I am getting only one plot. I put
figure
hold on (before the for loop) and
plot(X,Y,colorMap{i}); (inside the loop).
But still I am getting only one plot!

Do you want one figure for each A? if so put figure inside loop.
Otherwise makes sure you found all files, try a
disp(nFiles) in there
If nFiles>1 and you still only get one "plot" , check what color it has, maybe the contents of the files are all the same?
