[SciPy-dev] check_syevr_irange/check_syevr_vrange ?

[Arnd Baecker]

Hi,

to figure out a question related to a recent snapshot for windows
by Joe Cooper I installed on my debian sarge machine
a pretty recent scipy from CVS (see below).
For scipy.test(1) there are 4 errors, all related
to check_syevr_irange/check_syevr_vrange

I am not worried too much about the errors, as the results
seem pretty close.
Still I thought it would be better to report those here.

Best,

Arnd
