| | | | | | | | | | Fix a false mismatch. Separate dtype objects, even if equivalent, cause distinct array views to be created.

* | BUG: Fix masked median multiple masked arrays (#21999)Brigitta Sipőcz2022-07-172-1/+23
| | | | | | | | | | | | | | Fixed issue that occurs when trying to take the median of a list of masked arrays. Added a check to see if the input is a list then converts to a masked array. See issue #10757 for more information. Co-authored-by: jsclose <jsclose@umich.edu>
* | BUG: fix ma.minimum.reduce with axis keywordRuth Comer2022-07-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | Fixes the problem reported at https://github.com/numpy/numpy/pull/21977#issuecomment-1186082534 The reduce method here effectively calls itself with an unmasked MaskedArray (mask=nomask) and then expects either a MaskedArray or a scalar. This change ensures that an ordinary ndarray is converted to a MaskedArray, following the pattern already used in mean and var in this module.

* TST: Adding a test that MaskedArrays respect ufunc deferral heirarchyGreg Lucas2022-07-131-0/+64
| | | | | This test makes sure that a MaskedArray defers properly to another class if it doesn't know how to handle it. See #15200.
* ENH: Adding __array_ufunc__ capability to MaskedArrays.Greg Lucas2022-07-133-47/+194
| | | | | | This enables any ufunc numpy operations that are called on a MaskedArray to use the masked version of that function automatically without needing to resort to np.ma.func() calls.

* BUG: Use `keepdims` during normalization in `np.average` and `np.ma.average` ↵Srimukh Sripada2022-06-262-1/+10
| | | | | | | | | (#21851) The keepdims flag needs to be applied during the calculation of the sum of the weights in np.average and np.ma.average. Not passing it causes weights to broadcast incorrectly. Fixes #21850
* API: Define `<`, `<=`, `>`, `>=` for masked arraysSebastian Berg2022-06-212-1/+65
| | | | | | | | | | This defines the comparison operators (other than `==` and `!=`) explicitly for masked arrays. The mask is ignored for the resuling `res._data` (unlike `==` and `!=` which take the mask into account. Closes gh-21770, although the way that masked arrays propagate the fill-value seems generally broken and error prone.

| * | TST,MAINT: Simplify warning testing in masked arraysSebastian Berg2022-05-271-36/+18
| | | | | | | | | | | | | | | There is no point in catching the warnigns when raising will do (because we want 0 warnings). That is more informative in any case.
| * | MAINT: Fortify masked in-place ops against promotion warningsSebastian Berg2022-05-271-18/+24
| | | | | | | | | | | | | | | | | | These warnings are probably optional in the future. They should not matter much (since the following is an in-place op), but the `np.where` could upcast currently!

| | | | | | | | | | | | The test used unintialized values, if NaN happened to be there the test would fail (and generally, uninitialized values being used in tests is bad, since it shows up in valgrind).
