MATLAB: How do i create a recursive function that gives the number of digits in an integer? i.e. does the same that length function does in MATLAB

function

 function r = length_of(n)
 end
it seems to be easy but right now i'm stuck with it

As Wayne mentioned, recursivity in unnecessary, but if you had to implement a recursive function, you could have built something like:
 function r = length_of(n)
     if n < 10
         r = 1 ;
     else
         r = 1 + length_of(n/10) ;
     end
 end
