Regular expressions:

>> str = 'ABCD_01 36_00 3 .txt';
>> t = str2double( regexp(str,'.* (\d+)_.* (\d+)','tokens','once') )

t =
    36     3

If the filenames always start with four characters you can do:

>> filename = 'ABCD_01 36_00 3 .txt';
>> sscanf(filename, '%*4c_%*u %u_%*u %u.txt')

ans =

    36
     3
