MATHCAD AND CRYPTOGRAPHY

[ValeryOchkov]

Do you have more optimal (shorter) progtam for a task from this story http://en.wikipedia.org/wiki/The_Gold-Bug ?

See please too http://communities.ptc.com/docs/DOC-4736

Do you know others some stories for Mathcad?

You may use "match" and "on error" but it sure will not be good enough for educational purposes then.

Your routine returns a wrong result for strings just one character long - a tough problem for cryptographic character frequency methods .

You may also consider turning the routine into a function and making it ORIGIN-aware.

Maybe also adding a custom error message if the argument is the nullstring.

One foreign language is one method of CRYPTOGRAPHY!

So we are happily awaiting your language translation routine in Mathcad 😉

It will be good to see sheets!
