Why is numpy.cumsum (along axis=0) so much slower than a simple loop?
The same goes for numpy.add.accumulate
The reason is loop ordering. The reduction operator when using `cumsum`
or `add.reduce` does the summation in the inmost loop, whereas the

Hi,
I am relatively new to numpy and am seeking some advice on an
appropriate way to do the following simple task.
The idea is to build a class that will allow a user to easily remove
and keep columns and rows in a 2D numpy array.
An outline of the class is as follows:

This is not yet released (but will be in the near future):

You can at least use this as an example of how to add rows and columns
to a structured array. Or be an
hi,
I'm glad to inform you about new Python solver for multiobjective
optimization (MOP).
Some changes committed to solver interalg made it capable of handling
global nonlinear constrained multiobjective problem (MOP), see the page
for more details.
Using interalg you can be 100% sure

Hi All,
my apologies for my deep ignorance about math stuff; I guess I
should be able to find this out but I keep getting impossible results.
Basically I have a set of x, y data (around 1,000 elements each) and I
want to create 2 parallel curves (offset curves) to the original
one; parallel
Andrea,

by a constant offset, either positive or negative, in the direction of

Hello,
Say I have four corner points a = (X0, Y0), b = (X1, Y1), c = (X2, Y2)
and d = (X3, Y3):

Is there a function like meshgrid that would return me a grid of points
linearly interpolating those four corner points?
Thanks,
