Des matlab code required

I have designed an algorithm and now m trying to compare it with DES algorithm. I want the matlab working code for DES algorithm.

I have tried the following linklink, but it's not working.

http://www.mathworks.com/matlabcentral/fileexchange/37847-data-encryption-standard--des-/content/DES.m

Can anyone please help?

"It is not working" is a weak description of the problems you have. Please explain any details, such that it is possible to asssist you.

In this line... It's showing too many arguments

Can anyone please provide me with the correct code?

The code is not the problem. You need to pass input to the function instead of trying to use Run from the menu or from the tools. There are examples given in the File Exchange Contribution.

Note: we can barely discuss DES here. That one file has been approved by Mathwork's legal representatives, but we cannot discuss how it works due to legal restrictions of the USA.

Okay... Thank you

? At the link posted in the Question perhaps ?

Reminder: we cannot discuss how that File Exchange contribution works, for legal reasons. It exists, it was approved by Mathwork's legal team, and that is about all that we can say about it.
