Function has input and output. If it is only has input or only has output, we called this script or still function?

It is a function if the m-file beginning line contains the keyword function, otherwise it's a script. Scripts and functions Of course, if a function has no inputs and no outputs it's likely not of a lot of value unless it's reading/writing files or doing something else with side effects on the system as, having it's own workspace, anything being done inside it won't ever show up after it has completed its execution. Barring, of course, the use of assignin, evalin, etc., which are able to get access to the main workspace from a function, but use of those should be reserved for very special circumstances indeed.

A script operates in the workspace of the caller, e.g. the base workspace. It may use existing variables and may create new variables - in the workspace of the caller.
A function operates in its own workspace. A declaration statement, ... function(...), must be the first executable line of the function. It may have input and/or output arguments, or no arguments, e.g
function HelloWorld()
disp('Hello world')
end
