[Numpy-discussion] mirr test correctly fails for given input.

So is it a bug in the test or a bug in the implementation? The problem is that the slice values[1:] when values = [-12,39000,3,21000,37000,46000] contains no negative number and a nan is returned. This looks like a bug in the test. The documentation also probably needs fixing. Chuck _

[Numpy-discussion] filters for rows or columns

Hi list, I wonder if there is any smarter way to apply a filter to a 2 dimensional array than a for loop: a=array(...) idxList=[] for i in range(0,a.shape[1]): if (some condition on a[:,i]): idxList.append(i) thanks in advance. g ___

Hi Travis, The new parse_datetime.c file contains a lot of c++ style comments that should be fixed. Also, the new test for mirr is failing on all the buildbots. Chuck ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mai
