Hi there,
Dear Nancy,
Can you send me the code for encriting the image with the chaotic map.. I need to follow up that code with you to create another cryptography code from that, couse I am working on something like that.

Your best bet, if you don't want to write the code yourself, is to check the File Exchange, or use Google.

You gave no indication that you had already written code for it. You didn't attach your file, or tell people that you already had code where you needed improvements. I'm not an encryption expert so I can't help you with your code. I don't think there are many encryption experts here but I could be wrong. If you still need help/advice on your code, then please attach it (if you can legally, and you have no problem with others seeing your code), and someone may answer. Though usually the answers here involve syntax errors, error messages, simple program flow, etc., not complicated algorithm development. Good luck.
