Hi Numpy forum
Let me start out with a generic example:
In [3]: test_byte_str = .join([\x12\x03, \x23\x05, \x35\x08])
In [4]: desc = dtype({'names' : [HIGHlow, HIGH + low], 'formats': [uint8, ui
nt8]})
In [5]: r = rec.fromstring(test_byte_str, dtype=desc)
In [6]: r[0]
Out[6]: (18, 3)
In [7]:
OK, here we go for the stupid questions showing that I really don't
understaind building well:
I am building numpy on a Mandriva x86_64. I built an optimized ATLAS, and
added the relevant lines to the site.cfg so that numpy does find the
libraries. But now I get the following error at build:

Would clip do ? For native types, it should be relatively fast, in
particular if you use the argout

If I e.g. have

Can I get an exception automatically raised if ierr != 0?

Hello.
I was suppose to give more information, but after about two months(I am a
Python newbie, newbie to Matplotlib and newbie to Numpy plus a vacation
in-between).I finally tracked down the problem. However ... I see in
Matplotlib 0.98.5.2 the correction was made by somebody else. (Cry,

There was some recent discussion about the (inefficiency) of 'in' when
applied to a large xrange. I was wondering how numpy handled this and
found the following

a PDE over the missing region using the known pixels as boundary
