Re: [Numpy-discussion] nested loops too slow

Hi Nico, Using for-loops for numerical calculations is often problematic for numerical calculations. I don't understand the fancy stuff with the indexing of the arrays. Can you provide a working example script and/or a brief description of the calculation you are performing (including equations)?

[Numpy-discussion] nested loops too slow

2012-08-08 Thread nicolas aunai
Hi, I'm trying to write a code for doing a 2D integral. It works well when I'm doing it with normal "for" loops, but requires two nested loops, and is much too slow for my application. I would like to know if it is possible to do it faster, for example with fancy indexing and the use of numpy.cums
