[SciPy-User] generic_flapack.pyf and geqp3

[Collin Stocks]

Thanks :)
Actually, I already managed to figure out how to create the patch
before reading your post, but thanks for the quick reply anyway. Any
idea where I should go from here? I've submitted a patch to the
tracker (http://projects.scipy.org/scipy/ticket/1473). I guess I
should just wait...

It's just that there is some specific code I want to run (I have
already written it), and I would prefer that my code not rely on my
own personal fork of the SciPy project ;D

Actually, the code I have written is probably going to end up as part
of SciPy (or one of the SciKits), as it is a Python implementation of
the stepwisefit function from MatLab's statistics toolbox, which is
rather useful to some people. (Perhaps seeing this may be an incentive
for some of the developers to accept my patch for qr()...)
