storing filenames from directory

I would like to store filenames from a directory in a matrix. Filenames are of the following format:

11_1200.12.X

11_1201.37.X

11_1202.67.X

...

Where do you get these filenames from?

[Baba]

i have them in my directory. .X stands for any extention

fileinfo = dir('*.X');
fnames = {fileinfo.name};

Now fnames{1}, fnames{2} and so on will be the file names.

Note: the list will not necessarily be sorted. Use sort({fileinfo.name}) if you need it sorted.

if I wanted to just keep the part between _ and. (1200,1201,1202) would I need to convert? i tried -*. and that didn't work

[Walter Roberson]

namepart = cellfun(@(S) S(4:7), fnames, 'Uniform', 0);

If you prefer it in numeric form, you can use

namepart = cellfun(@(S) str2double(S(4:7)), fnames);
