| * | MAINT: Fixes for problems in numpy/lib revealed by pyflakes.Charles Harris2014-07-3114-73/+66
| | | | | | | | | | | | | | | | | | Some of those problems look like potential coding errors. In those cases a Fixme comment was made and the offending code, usually an unused variable, was commented out.
| * | STY: PEP8 compliance for numpy/lib/tests.Charles Harris2014-07-319-243/+243
| | | | | | | | | | | | | | | | | | | | | The possibly controversial part of this is making the nested array value lists PEP8 compliant, as there is something to be said aligning the values for clarity. In the end, it seemed like the easiest thing to do was to make them PEP8 compliant. The eye can get used to that.

| * | MAINT: Change default inplace, ufunc(...,out=x) casting to same_kind.Charles Harris2014-05-061-1/+5
| | | | | | | | | | | | | | | | | | There has been a warning of this change since numpy 1.7. numpy 1.10 is a good time to do it. The nanvar function needed a fix after the change, and the tests and documentation are updated.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following inequality causes wrong counting at the edges and can be avoided by making the edge array of the same type as the input data.

* | | BUG: Fixed piecewise function for 0d inputJuan Luis Cano Rodríguez2014-06-082-20/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When `x` has more than one element the condlist `[True, False]` is being made equivalent to `[[True, False]]`, which is correct. However, when `x` is zero dimensional the expected condlist is `[[True], [False]]`: this commit addresses the issue. Besides, the documentation stated that there could be undefined values but actually these are 0 by default: using `nan` would be desirable, but for the moment the docs were corrected. Closes #331.
* | | BUG: Correct behavior for lists of tuples in unique, closes #4785jaimefrio2014-06-062-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | np.unique produces wrong results when passed a list of tuples and no keyword arguments, as it fails to recognize it as a multidim array, but handles it as a 1D array of objects. The only way around this seems to be to completely eliminate the fast path for non-array inputs using `set`.

* | | BUG: fix test deleting temporary file before using it on windowsJulian Taylor2014-06-031-22/+28
| | | | | | | | | | | | | | | | | | | | | The version check was not valid for python3, though the whole logic can be removed with a finally clause. This requires that the savez tests need to cleanup the NpyzFile results which still hold an open file descriptor.

| * | | | ENH: add storage format 2.0 with 4 byte header length sizeJulian Taylor2014-06-022-34/+194
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new format only increases the header length field to 4 bytes. allows storing structured arrays with a large number of named columns. The dtype serialization for these can exceed the 2 byte header length field required by the 1.0 format. The generic functions automatically use the 2.0 format if the to be stored data requires it. To avoid unintentional incompatibilies a UserWarning is emitted when this happens. If the format is not required the more compatible 1.0 format is used. Closes gh-4690

* | | | MAINT: Comparison deprecation followup fixesSebastian Berg2014-05-041-15/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Makes the identity check `a = np.array([np.nan], dtype=object)` `a == a`, etc. a deprecation/futurewarning instead of just changing it. Also fixes some smaller things.
* | | | DEP: Deprecate that comparisons ignore errors.Sebastian Berg2014-05-041-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This means that for example broadcasting errors get raised. The array_equiv function is changed to explicitely test if broadcasting is possible. It may be nice to do this test differently, but I am not sure if that is possible. Create a FutureWarning for comparisons to None, which should result in areal elementwise (object) comparisons. Slightly adepted a wrong test. Poly changes: Some changes in the polycode was necessary, the one is probably a bug fix, the other needs to be thought over, since len check is not perfect maybe, since it is more liekly to raise raise an error.

* | | ENH: add a 'return_counts=' keyword argument to `np.unique`jaimefrio2014-04-052-37/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds a new keyword argument to `np.unique` that returns the number of times each unique item comes up in the array. This allows replacing a typical numpy construct: unq, _ = np.unique(a, return_inverse=True) unq_counts = np.bincount(_) with a single line of code: unq, unq_counts = np.unique(a, return_counts=True) As a plus, it runs faster, because it does not need the extra operations required to produce `unique_inverse`.
