[Numpy-discussion] Unicode revisited

Hey all, Ondrej has been working hard with feedback from many others on improving Unicode support in NumPy (especially for Python 3.3). Looking at what Python has done in Python 3.3 (PEP 393) and chatting on the Python issue tracker with the author of that PEP has made me wonder if we aren't

Re: [Numpy-discussion] 2 greatest values, in a 3-d array, along one axis

Thanks for each of the improved solutions. The one using argsort took a little while for me to understand. I have a long way to go to fully utilize fancy indexing! -- jv On 8/3/2012 10:02 AM, Angus McMorland wrote: On 3 August 2012 11:18, Jim Vickroy > wrote:

Re: [Numpy-discussion] 2 greatest values, in a 3-d array, along one axis

Here is the 3D implementation: http://pastebin.com/ERVLWhbS I was only able to do it using a double nested loop, but I am sure someone more clever than me can do a slicing trick to overcome it. Otherwise, I hope this is fast enough for your purpose. David. On Fri, Aug 3, 2012 at 4:41 PM, Daπid

Re: [Numpy-discussion] 2 greatest values, in a 3-d array, along one axis

Here goes a 1D simple implementation. It shouldn't be difficult to generalize to more dimensions, as all the functions support axis argument: >>> a=np.array([1, 2, 3, 5, 2]) >>> a.max() # This is the maximum value 5 >>> mask=np.zeros_like(a) >>> mask[np.argmax(a)]=1 >>> a=np.ma.masked_array(a, ma

[Numpy-discussion] 2 greatest values, in a 3-d array, along one axis

Hello everyone, I'm trying to determine the 2 greatest values, in a 3-d array, along one axis. Here is an approach: # -- # procedure to determine greatest 2 values for 3rd dimension of 3-d array ... import numpy, numpy.ma xcnt, ycnt, zcnt =
