Hi,
i'm sorry, if it is a FAQ, but i have a problem with the following
question.

I want to find two nonsingular matrices P and U with

            | U |   u
    P * N = |   |
            | 0 |   (n - u)  (this i a nul, not a big O!).

whereby N is a (n*u) Matrix (with Rank u). In the article, the author
said, i can use a PU-factorization, but i never heard of it (i'm not
a mathematical student).

So, can anybody give me a hint, an article, in which it's described or
a book (perhaps, a book or an article, which i can get in germany :->,
- the book or the article can be in english !).

Thanks for any help,
Volker
