[Numpy-discussion] deprecations for 1.6; assert_almost_equal

2011-03-06 Thread Ralf Gommers
Hi, I went through the current deprecations, and removed a number of things that have been deprecated for a long time, see https://github.com/rgommers/numpy/commits/deprecations-1.6. I'll commit that unless anyone objects. If anyone has new deprecations they want to put in for 1.6, discussing the

Kahan summation algorithm? pairwise summation? Looks like BLAS does not use these algorithms. I'm curious to know which algo are coded in matlab/scilab. Another issue is that sum is slow. Xavier > for the sum function part, > It's not a good way to fix but... if you want more accuracy > > x=(np.
