* BUG: lib: Fix handling of integer arrays by gradient.Warren Weckesser2020-01-052-4/+47
| | | | | | | In numpy.gradient, convert integer array inputs to float64 to avoid unwanted modular arithmetic. Closes gh-15207.

* REV: Revert "Merge pull request #14794 from mattip/nep-0034-impl"Charles Harris2019-12-042-20/+15
| | | | | | | | This reverts commit 3a9a63f81aa37b48bc3eb4efdc2e695210805aa5, reversing changes made to 7999f7c038a50d79b06edf2d45eb5ff2c25a5a42. A lot of problems have been exposed by this change, so best to leave it out of the 1.18.x series and work on it in master.

* | | ENH,DEP: Allow multiple axes in expand_dims (#14051)Larry Bradley2019-12-022-32/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | This PR allows the axis keyword in expand_dims to be a tuple of ints. Previously, axis could only be an int. This issue was previously discussed in gh-12290 and the changes are based on gh-12290 (comment). This PR also removes the deprecation added in v1.13 (2017-05-17), where previously axis could be outside of the range (-a.ndim - 1) <= axis <= a.ndim. Such an axis value will now raise an AxisError. Please let me know if it's too soon to remove this deprecation (I could not find any dev docs stating the length of the numpy deprecation cycle). Closes gh-12290.

* | BUG: lib: Fix histogram problem with signed integer arrays.Warren Weckesser2019-10-152-5/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An input such as np.histogram(np.array([-2, 0, 127], dtype=np.int8), bins="auto") would raise the exception ValueError: Number of samples, -1, must be non-negative. The problem was that the peak-to-peak value for the input array was computed with the `ptp` method, which returned negative values for signed integer arrays when the actual value was more than the maximum signed value of the array's data type. The fix is to use a peak-to-peak function that returns an unsigned value for signed integer arrays. Closes gh-14379.
