Re: [Numpy-discussion] Help with interpolating missing values from a 3D scanner

I have implemented an iterative gaussian smoothing approach that is working well for my purposes. My approach uses a median filter to populate the initial values and then runs a few passes with gaussian smoothing. This works very well for the missing values that I care about within the f

Re: [Numpy-discussion] efficient usage of tensordot

This is not the first time this issue is raised here. You may try this piece of code, which may take less memory: (A*x).sum(axis=1).T Nadav -הודעה מקורית- מאת: numpy-discussion-boun...@scipy.org בשם Gideon Simpson נשלח: א 18-ינואר-09 07:30 אל: Discussion of Numerical Python נושא: [Nu
