* MAINT: Use moveaxis instead of rollaxis internally (#9475)Nico Schlömer2017-08-101-7/+7
| | | | | Also add a hint to the documentation advising the use of moveaxis over rollaxis. Tests for rollaxis are left alone.
* MAINT/DOC: Use builtin when np.{x} is builtins.{x}.Eric Wieser2017-08-051-9/+9
| | | | | | | This is the case for x in {int, bool, str, float, complex, object}. Using the np.{x} version is deceptive as it suggests that there is a difference. This change doesn't affect any external behaviour. The `long` type is missing in python 3, so np.long is still useful
* MAINT: Changed diff to use iterative instead of recursive approachJoseph Fox-Rabinovitz2017-07-311-23/+31

* MAINT: Use _validate_axis inside _ureduceEric Wieser2017-03-281-17/+14

* MAINT: Reuse _validate_axis in np.gradientEric Wieser2017-03-281-13/+2
| | | | | | | This also means that its axis argument invokes operator.index like others do. _validate_axis currently accepts lists of axes, which is a bug.

* ENH: gradient support for unevenly spaced dataAlessandro Pietro Bardelli2017-02-221-84/+235
| | | | | | | | | | | | | This somehow reverts #7618 and solves #6847, #7548 by implementing support for unevenly spaced data. Now the behaviour is similar to that of Matlab/Octave function. As argument it can take: 1. A single scalar to specify a sample distance for all dimensions. 2. N scalars to specify a constant sample distance for each dimension. i.e. `dx`, `dy`, `dz`, ... 3. N arrays to specify the coordinates of the values along each dimension of F. The length of the array must match the size of the corresponding dimension 4. Any combination of N scalars/arrays with the meaning of 2. and 3.
* MAINT: Use normalize_axis_index in all python axis checkingEric Wieser2017-02-201-9/+4
| | | | | | | As a result, some exceptions change from ValueError to IndexError This also changes the exception types raised in places where normalize_axis_index is not quite appropriate

* BUG: handle unmasked NaN in ma.median like normal medianJulian Taylor2016-12-121-17/+1
| | | | | | | | | | | This requires to base masked median on sort(endwith=False) as we need to distinguish Inf and NaN. Using Inf as filler element of the sort does not work as then the mask is not guaranteed to be at the end. Closes gh-8340 Also fixed 1d ma.median not handling np.inf correctly, the nd variant was ok.
* MAINT: let average preserve subclass information.Marten van Kerkwijk2016-11-191-13/+1
| | | | | | This behaviour matches that for most other numpy functions (such as np.mean). It was initially slated for 1.12, but replaced by a FutureWarning. Hence, this is for 1.13.
