I wanted to point anybody interested to a blog post that describes a
useful pattern for having a NumPy array that points to the memory
created by a different memory manager than the standard one used by
NumPy. The pattern shows how to create a NumPy array that points to
previously allocated
Hi, can anyone point me in the direction of some example code to use
the norm_gen function in scipy.stats? I know this is the wrong board
but I seem to be at the wrong end of the moderation queue on the scipy
board and have been for a couple of weeks, so my posts over there

I will be branching for 1.2.0rc2 shortly. Please don't commit
anything to the branch without running it by the list:
http://projects.scipy.org/scipy/numpy/browser/branches/1.2.x
Once the binaries have been made, I will send out an announcement.
Thanks,

Nope.
When you use compressed(), you get a ndarray (or a subclass, de

what is the "100,000 to 1 sum." this is my interpretation:
