How to get digits ( e.g.telephone number) from user and treat each digit separately?

Hello. My problem is I want to get digits (e.g.telephone number) from user, like 079389482, but the length of digits unknown. And I want to work on each digit separately, to build dtmf signal (plot) for each digit

How are you getting the digits from the user?

There are many ways. But right now Im trying this: prompt={'Enter your digits by space:'}; title='Dial'; numbers=inputdlg(prompt,title); digits = str2num(numbers{1}); %And I can choose every digit like this a = digits(2); disp(a);

If you get the digits as a string then this is easy by simply subtracting '0' from the string:

>> S = input('Please enter your telephone number: ','s');
Please enter your telephone number: 72643
>> V = S-'0'
V =
   7   2   6   4   3
