[SciPy-dev] [patch] RQ decomposition

[Andrew Straw]

(I would submit this straight to Trac, but as I can't log in, I'm 
sending it to the list in case I don't get back to this for a while.)

I attach a patch that implements RQ decomposition (similar to the QR 
decomposition). This is basically a touch up of Harry Kalogirou's patch 
of 2 years ago. His original patch can be found at 
http://projects.scipy.org/pipermail/scipy-dev/2005-July/003075.html My 
version converts his code to numpy, adds checks to exclude non-square 
and complex matrices (I couldn't get them to work in the time I tried, 
this is listed as TODO in the source code comments), and performs some 
tests on the correctness of the answers. If a committer could commit 
this or give me feedback, that would be great.

Cheers!
Andrew
