So if I have a 2-dimensional array, and I want to return the indexes
of all the elements that are larger than some value, then I just use

Hello,
My analysis shows that the exponential regression gives the best result
(r^2=87%)--power regression gives worse results (r^2=77%). Untransformed
data gives r^2=76%.
I don't think you want lognorm. If I'm not mistaken, that fits the data to
a log(normal distribution random variable).

Hi all:
I'm just writing to report on my experience using Starcluster, which enables
the use of NumPy and Scipy in the Amazon EC2 cloud computing environment.
The purpose of my email is to extol Starcluster's qualities, and suggest
that the NumPy community be aware of its development.I suspect

Oh no, that's not what I meant when I asked you if you had installed Xcode.

Eric,
Yes, I downloaded the files recommended on that webpage. The tar.gz files
unpack, but they do not install, and I am too much of a newbie to figure out
how to install the files in the unpacked folder. No matter where I placed
the numpy folder, I couldn't get Python 2.6 to find and install n

Hi,
Functions that call _nanop (i.e. nan[arg]min, nan[arg]max) currently fail with
unsigned integers. For example:
>>> np.nanmin(np.array([0, 1], dtype=np.uint8))
OverflowError: cannot convert float infinity to integer
It seems that unsigned integers don't get identified as integers in the _na
Yes, for efficiency reasons matplotlib will use a reference to original
data whenever possible, rather than copying it. Also, when using the
pylab/pyplot API, matplotlib figures also stay around until they are
explicitly deleted. You may need an explicit call to "clf('all')" to
remove the fig
yes, a GTK app from the python shell. And not using the toolbar.
I'll see if I can extract out a sample of code that demonstrates the problem
I'm having.
