The user can enter expressions, like pi/4 or rand(3) , and can use variables in the workspace. If the user presses the Return key without entering anything, then input returns an empty matrix.

What is an output argument in MATLAB?

When you use a function as part of an expression, such as an if statement, then MATLAB® calls the function with one output argument. Therefore, the nargout function returns 1 within expressions.
