Put your wife in matlab variable. and take 1000 derivative of your wife. Result will tell you. hahha

Nice, Important thing is to get the size right!

Andrew Newell on 6 Jun 2013

The question says 'regardless of input', which I take to mean that more than one input is allowed. I think this should be added to the list of tests:
U = cell(1); R = struct; wiferight(@who,'do you think',U,R,'God?')

I have a doubtt when I try to write this code using anonymous function i.e., wiferight=@(in)'out' and cecked the output in MATLAB 2007b version it gave me the correct answer why is it giving a wrong answer I am unable to understand it.

Sneha, do you really want to tell your wife to get 'out'?

Aditya Jain on 1 Sep 2016

Isn't it suppose to be a function? Atleast 16a MATLAB thinks your code is a script not a function

Star0397 on 20 Jul 2015

How can this solution code have a size of 8? It's ONE LINE!

the cyclist on 21 Jul 2015

There is a nifty trick for reducing what seems like the shortest possible solution. I don't really want to just state the trick, as it is fun to learn or discover on your own.

If you can't figure it out, I suggest that you submit a simple problem to Cody, and look at the solutions. (They will all be viewable to you, as the problem submitter.) Someone will use the trick, almost certainly.

Mostafa on 17 Oct 2016

So does this trick work in the actual application as well, or is it related to how Cody calculates the code size?
I mean will this "trick" actually improve the performance in Matlab env?

the cyclist on 18 Oct 2016

No, the trick is actually fairly poor coding practice
