Hi I am trying to extract a file name but i don´t want to extract it´s entire name.For example if i have 30 people with 3 different expressions each. I name them as 0101.txt...0103.txt,...,3001.txt...3003.txt. How could i extract only the first 2 digits that represent individual person? Thank you.

If I got you question right
cac = { '0101.txt', '0103.txt', '3001.txt', '3003.txt' };
out = regexp( cac, '^\d{2}', 'match' );
out{:}
outputs
ans =
'01'
ans =
'01'
ans =
'30'
ans =
'30'
