re: matrix manupulation

What you're describing makes no sense.

You need to be able to communicate in detail what you're trying to do. What is your starting condition, what is your end condition. If you know another programming language, show us this code in that language and maybe we can just do a translation for you. Either way, you're just going to need to explain it more clearly, as what you've said so far is gibberish.

All I've understood so far is that you're starting with an array. There's lots of things that you can do with arrays, what are you trying to do?
