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

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{:}))
