- 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
