Docstring bug.
But it behaves right.

As for me, I used empty matrices in MATLAB as well as python rather often.
Simple example:
from numpy import array, hstack
#...
m = A.shape[1]
a = array(()).reshape(0,m)
for i in some_ind:
a = hstack((a, A[i]))
for i in some_ind2:
a = hstack((a, Aeq[i]))
return a
other example:

It does. See the documentation of the warnings module for the full
syntax and fine grained control.

Hi,
I was wondering what an empty matrix is, and what it is useful for
(by empty matrix, I mean something created by numpy.matrix([])) ? Using
those crash some functions (see for example scipy ticket #381), and I am
not sure how to fix this bug.

Well, quite the contrary, it is as quick as it can be. If you think it
is too slow, don't hesitate to help :)

Ok I'll try that although I guess that it turns off all warnings. that
I'm concerned as well that scipy's release cycle isn't as quick as it
could be.

Hi,
Is there going to be a scipy release anytime soon?
I'm using numpy 1.0.3 with scipy 0.5.2 and I get these ugly warnings all
the time:
c:\apps\python25\lib\site-packages\scipy\misc\__init__.py:25:
DeprecationWarning: ScipyTest is now called NumpyTest; please update
your code
test = Scip
Does anyone know if Numpy's covariance calculation function, cov(),
which is located in /numpy/lib/function_base.py calculate the
covariance matrix of complex data correctly?
I.e., does it implement something like ,
P = cov(X) = 1/(N-1) * \Sum_i ( X[:,i] * transpose(X[:,i].conj()) )
