pseudo fprintf user defined function

Wai Kwan — Mon, 09 Nov 2009 03:39:02 -0500

Hello all,

I feel bad for asking a silly question here but I am still a freshie on MATLAB.
I am having an assignment from university and apparently I was asked to prepare a new function which is similar to fprintf.

The function should be able to act like fprintf,just for the string printing part only.
The emulated function should be able to behave differently if you supply return variable
(ret = fprintf('hi') % prints `hi' and assign 2 to variable ret) and if you do not supply such return variable (fprintf('hi') % just prints `hi').

I have been stuck for days.Seriously need all of your help A.S.A.P.
Thanks in advance.

Warmly,
WaiKwan

So, what have you tried so far?
Or do you expect us to do your homework for you?
And if we do this, will you submit it and claim it as your own work?
Honestly, I really want to help you, but I'm afraid that if I do so,
that will make you a liar and a cheat.
Perhaps the best thing would be if you posted your professor's email,
then we can submit our solution to your homework directly to him
pointing out the dilemma that we are facing.

Hi tideman,
For your first question,I have tried using "char"function and "sprintf"function to print out this string.And I failed to suppress the length of the string as I wish.
2nd question,no i want to do my work my own.
3rd,I am seeking advice here.If I could figure that myself,do I need to post my trouble here?
And thanks for reading my post and take your time replying this.
I sincerely thank you if you wish to care.I also welcome you if you feel like lecturing me.
=)

We'd like to help you, but you didn't actually ask a question in this
posting ... if you ask a question about a specific section of the code
you've written and show us that code, it's much more likely that we'll
actually be able to help you.

As a guess, I suspect you're not sure how to differentiate between the
output argument/no output argument cases. If so, look at HELP NARGOUT.

Hi Steven,

Thanks for the reminder on nargout function part. Using this method,I did solve my problem.
Thanks again for the guidance. =)
