Step by step execution of "No argument function"

I am calling a no argumnet function in my main .m file.

I want to execute this function step by step to debug and check the folw of the fucntion code.

But it is giving error of "Not enough arguments". I want to make sure MATLAB provide this facility to execute this type of fucntion step by step because MATLAB is user friendly software.

YOu can do that.......but you have to provide input arguments to the function if any function is called in the code.

Will you please give me an example:

Because when I want to do it in the command window to execute step by step, it gives error of "no enough arguments".

I did not see such a message yet. Maybe it concerns inpur or output arguments? Please post the relevant part of the code and a copy of the complete message. Otherwise it is hard to guess, what you are doing and which problem occurs.
