using function input to create a title

Hello, I am currently writing a function which takes an input, creates a structure based on the size of the input, and sends it to a dot file.

My problem is that i want the dot file to be saved as different things based on the input. ie if I input function(5) i want the five to be incorporated into the name of the outgoing dot file.

incToDot(inc,8.0,8.0,1.0,'nameoffile.dot');

 i would really like the output of file to be nameoffile#.dot   where # is the size of the input value for the function. I am confused on how to do and any help would be great.

N = 5;  % An integer to use in the string below...
str = sprintf('nameoffile%i.dot',N)  % Make a string.
% Use the above for integer N to make your string, then use it:
incToDot(inc,8.0,8.0,1.0,str);
