Suppose I have a function which requires no inputs. Should I indicate it with parentheses () or leave it naked? Both cases work, but is there a convention in the MATLAB community?
Example:
someFunction
% do sth
end
vs
someFunction()
% do sth
end

If a function requires no inputs, I prefer to use () after calls to it. It is unambiguous, and saved remember whether the name is a function directly or a function handle (function handles require the () to call them)

If I am creating a function with no arguments then it is most likely because I am answering a question here, tossing together something of no lasting importance. In such cases I usually do not bother to put the () in the function definition. In my own code, I do not typically have functions with no parameters.
