I’d like to know if there is any way to overwrite fprintf built-in function? I wan to add some my own action in fprintf function before I call the built-in fprintf. I know how to overwrite disp, but I do not know how to overwrite fprintf. I’d like to know if it is possible. Could you please help? Thanks.

You cannot overwrite it, but you can mask it. Put a new M-file in your directory called 'fprintf.m' Then when you call FPRINTF, MATLAB will actually call your function. From within your function, you can access the built in version by using the BUILTIN function.

I will leave alone questions of why you would want to overload such a great function in the first place!
