Hi, I have a list of data file name below :

Data_T2_31_4c_comb_1_9-10-11-12.mat

Data_T2_31_4c_comb_2_9-10-11-13.mat

...

Data_T2_31_4c_comb_3876_25-26-27-28.mat

I would like to extract the number in the 20th character, so that I will have a list of increasing integers [1 2 .. 3876]. Could you show me how to do that please ! Winn

s={'Data_T2_31_4c_comb_1_9-10-11-12.mat'
 'Data_T2_31_4c_comb_2_9-10-11-13.mat'}
out=regexp(s,'\d+','match')
out=str2double(cat(1,out{:}))
