Have you read the Matlab Getting Started Guide?
Read Scripts and Functions under Programming:
Open the Matlab editor and declare your function.
function output = my_fun(N)
end
It seems to me that your user will input only N and then your function will do the rest of the work.
Write your code in the function body (between the function declaration and the end statement)
Save the function as my_func.m in a folder on the Matlab path and execute your function, ex:
>> outsum = my_func(10);
