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.

As others have already mentioned, you should use the DIR function to list files in a directory.

If you are still looking, here is an example to show how to use the function:

dirName = 'C:pathofolder';              %# folder path
files = dir( fullfile(dirName,'*.xyz') );   %# list all *.xyz files
files = {files.name}';                      %'# file names

data = cell(numel(files),1);                %# store file contents
for i=1:numel(files)
    fname = fullfile(dirName,files{i});     %# full path to file
    data{i} = myLoadFunction(fname);        %# load file
end

Of course, you would have to supply the function that actually reads and parses the XYZ files.
