use part of file name

I have a directory with files in following format AAA_100_0.dat, AAA_100_1.dat, AAA_100_2.dat, and so on

Id like to be able to pull off parts of the file names for instance the number between two underscores which is 100 in this case, and the numbers between underscore and period, which increment in this case.

Thank you

Answer 1

[per isakson]

    sad = dir('AAA*.dat');
    name_list = { sad.name };

captures the file names

    cac = regexp( name_list, 'AAA_(\d+)_(\d+)\.dat', 'tokens' );

should (I have not tested) extract the numbers

fls = dir('AAA*.dat')
fn = {fls.name}
c = regexp(fn, '\d*', 'match' )
out = str2double(cat(1,c{:}))
