I have emailed this list in the past explaining what is driving my open source efforts now. Here is a blog-post that may help some of you understand at little bit of the history of Blaze, DyND Numba, and other related developments as they relate to scaling up and scaling out array-computing in Pyt

Along those lines, yes, but you have to be careful of even/odd dimension lengths. Would be nice if it was some sort of stride trick so that I don't have to allocate a new array twice as we do in the concatenation steps. Cheers! Ben Root On Tue, Mar 29, 2016 at 1:58 PM, Joseph Fox-Rabinovitz < jf

Is there a quick-n-easy way to reflect a NxM array that represents a quadrant into a 2Nx2M array? Essentially, I am trying to reduce the size of an expensive calculation by taking advantage of the fact that the first part of the calculation is just computing gaussian weights, which is radially symm

I just tested those new openblas-based wheels on the linux virtualbox setup that I used to report the following segfault back in February: https://mail.scipy.org/pipermail/numpy-discussion/2016-February/074866.html https://mail.scipy.org/pipermail/numpy-discussion/2016-February/074870.html I cann
