process a list of files with a specific extension name in matlab

Question

How can I process all the files with \".xyz\" extension in a folder? The basic idea is that I want a list of file names and then a for loop to load each file.

Answer 1

Here is my answer:

dirName = 'E:\My Matlab\5';
[sub,fls] = subdir(dirName);
D = [];
j = 1;
for i=1:length(sub),
    files{i} = dir( fullfile(sub{i},'*.xyz') );
    if length(files{i})==1
        D(j) = i; 
        files_s{j} = sub{i}; 
        j=j+1;
    end
end

varaible files_s returns the desire paths that contain those specific data types!
