collect and extract numbers to/from number

Hi everyone how to collect some numbers (ex: 10,23,14,17 ) to be one number for example be 200 (according to ciphering method)and how to extract these four numbers from 200 number (according to deciphering method)

regards

Majid - please describe why are attempting this. Do you have algorithm already that will somehow map four (or more or less) numbers to a single number, which you will then decode back to the original four? Are your numbers always two digits, or can they be 1 or 5 or 342? What is the range of your input numbers - is it from 0 to 256?

Try using inputdlg to get the 4 numbers. Call them a, b, c, and d. Then just do your algorithm, for example

a=10;
b=23;
c=14;
d=7;
% Encode by stitching together.
string = sprintf('%2.2d%2.2d%2.2d%2.2d', a,b,c,d)
number = str2double(string)
% Decode
aRecovered = int32(number/1e6)
bRecovered = mod(int32(number/1e4), 100)
cRecovered = mod(int32(number/1e2), 100)
dRecovered = mod(int32(number), 100)

In the command window:

string =
10231407
number =
    10231407
aRecovered =
          10
bRecovered =
          23
cRecovered =
          14
dRecovered =
           7
