Accessing a specific char in a string

I am trying to access a specific char in a string.

I get a number by the user and I need to index all the digits, because the number is saved in a vector the only way to access it will be by using the mod operation.

So I thought of a shorter way, because the number is an integer, I can turn it into a string and then use an index to access the desirable.

For example:

A=num2str(18345); A(2) 8

Can I access the char without saving in to a variable first? num2str(18345)(2) does not work

Thanks

a = 18345 ;
iwant  = num2str(a) - '0' ;

iwant is a double, you can access any index.
