Hi, I would like to import files from a directory. The files have the following sequence:
Data 11
Data 12
Data 13
Data 21
Data 22
Data 23
Data 31
Data 32
Data 33
I usually use the following general code for extracting a sequence of files:
numfiles = 3;
mydata = cell(1, numfiles);
for k = 1:numfiles;
myfilename = sprintf('Drift.out', k);
mydata{k} = importdata(myfilename);
end
Can anyone please advise me on how to modify it to suit the above files sequence?
Thank you very much. Regards, Ismail

files = dir('*.out') ; % get all files with extension out
N = length(files) ; % toal number of files
% loop for each file
for i = 1:N
filename = files(i).name ;
% do what you want
end

What ever the names may be......it will list all the files present in the folder with extension out.

Thanks KSSV. I could not get the code right yet. I actually mean I need to identify the sequence of each file based on its name and permutation number in order to plot the data from the two files. I tried using this file, but I don't know what the thing that is wrong with it.
c = [1 2 3];
s = [1 2 3];
for i=1:3;
for j=1:3;
b=importdata['react.out', ij];
a=importdata['Drift.out', ij];
plot(a(:,2),-sum(b(:,2:11),2));
x= a(:,2);
y= -sum(b(:,2:11),2);
end
end
