Hey,
the array comparisons == and != never raise errors but instead simply
return False for invalid comparisons.
The main example are arrays of non-matching dimensions, and object
arrays with invalid element-wise comparisons:
In [1]: np.array([1,2,3]) == np.array([1,2])
Out[1]: False
In [2]:
I can see where you are getting at, but I would have to disagree. First of
all, when a comparison between two mis-shaped arrays occur, you get back a
bone fide python boolean, not a numpy array of bools. So if any action was
taken on the result of such a comparison assumed that the result was
Hi Scott, thanks for your help.

Hi,
I use masked arrays to mark missing values in data and found it very
convenient, although sometimes counterintuitive.
I'd like to make a pool of masked arrays (shared between several
processing steps) read-only (both data and mask property) to protect
the arrays from accidental modification

is perfectly fine, but it does not work on ma-s. Moreover, mask

I'd expect).

The docs for numpy.sign at

do not indicate how complex numbers are handled. Currently, np.sign
appears to return the sign of the real part as a complex value.

I don't see advantage to this change and the reason isn't good enough to
justify breaking the interface I think.
But I don't think we rely on this, so if the change goes in, it probably

Hi all,
FYI new free software for knapsack problem (
http://en.wikipedia.org/wiki/Knapsack_problem ) has been made (written in
Python language); it can solve possibly constrained, possibly (with interalg )
nonlinear and multiobjective problems with specifiable accuracy. Along with

Hi All,
I've been working on Benjamin's PR, which I took down as he didn't have
time to finish it. I've made the following changes and thought I'd run them
past others before putting up a new pull request.

NumPy Folks,
I want to load images with PIL and then operate on them with NumPy.
According to the PIL and NumPy documentation, I would expect the
following to work, but it is not.

[GCC 4.7.3] on linux2

NumPy Folks,
Sorry for the self-reply, but I have determined that this may have
something to do with an alpha channel being present. When I remove the
alpha channel, things appear to work as I expect. Any discussion on
the matter?
