Hi, I have another question. I have a big number something like 200308091234562. I would like to appeal to indicated parts. To other calculations.
So I would like to have something like this from this big number.
A = 2003 B = 08 C = 09 D = 123
Which funtion should I use. Thank You.

@ZK: Please post the type of the variable, which contains the shown value. Use the Matlab command class() to find out the type in case of doubt. Numbers do not have a leading zero and in '08' it is surely not the '0' which indicates that it is August, but the '8'.

I suggest treating this numerical value as a string ('chararcter array') and us such operations, e.g.
s='200308091234562'
A=s(1:4)
Maybe you want to do math with it afterwards:
str2num(A)*2

If 200308091234562 is a double:
d = 200308091234562
A = floor(d / 1e11);
B = rem(floor(d / 1e9), 100);
C = rem(floor(d / 1e7), 100);
D = rem(floor(d / 1e4), 1000);
If the value is a string:
s = '200308091234562'
A = s(1:4);
B = s(5:6);
C = s(7:8);
D = s(9:11);

OK. Jan Simon, thank You for answer and patience. I will express more precisely my problems in future.
I would like convert {1x1} cell to string because for this method reading numbers is most clear for me. Can You present me a good formula for it?
