* DOC: Parameter name typo axes -> axis in numpy.fft._pocketfft.Matthias Bussonnier2020-12-181-5/+5
| | | | | | | | | | The parameter name seem to have a typo in both those case and reference axis (and not axes), this is likely due to copy-past as some other functions in this modules use axes (when several indices are required), but other also use `axis` and have the correct spelling. From review it also seem like previous phrasing is unclear so update all similar entries to reflect the new phrasing.

| * BUG: Remove non-threadsafe sigint handling from fft calculationSebastian Berg2020-06-251-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fft calculation is the only point in our code where this function is used. Allowing Ctrl+C, in FFT specifically used have more reasons, since before pocketfft, some array-sizes could lead to very large run-times. Pocketfft fixed that issue, and now FFT is not really any slower, faster, or memory hungry than any other NumPy operation so it feels it does not need this handling. Rather, if we can find a better solution, it should also be added to more functions. The reason for removal is that it is not only unsafe while the FFT is running (in theory). Multiple, threaded FFT run can easily leave the signal handler in a bad state, causing crashes if Ctrl+C (sigint) is given at any point after the call. It would be possible to patch that over, by only resetting the signal handler if we actually changed it (or even more complex tricks), or possibly only using this technique when on the main thread. But, all of these solutions seem to complicate things, when the main reason for why allowing sigint seems useful is gone with pocketfft.
* | ENH: add `norm=forward,backward` to numpy.fft functions (#16476)Chris Vavaliaris2020-07-123-106/+259
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kwarg option norm=inverse leads to scaling of the transforms inverse (opposite) to that of the default option norm=None; i.e. the forward transform is normalized with 1/n whereas the backward one with 1. The fft routines and their tests have been modified to reflect the changes; all tests have been passed successfully. Closes #16126 * modified _unitary, fft & ifft and their tests; tests passed * modified rfft & irfft and their tests; tests passed * modified hfft & ihfft and all tests; all modifications are now done * correction in ihfft; all 79 fft tests passed successfully * undo unnecessary docstrings changes made in my previous commits * use norm=forward kwarg value name * Update numpy/fft/__init__.py Co-authored-by: Leo Fang <leofang@bnl.gov> * add code review suggestions Co-authored-by: Leo Fang <leofang@bnl.gov> * add default norm=None alias norm=backward * streamline private normalization functions * modify hermitian FFTs * add review suggestions Co-authored-by: Leo Fang <leofang@bnl.gov> * add review suggestions v2 (dict as module const) * make review suggestions v3 * Apply suggestions from code review Co-authored-by: Leo Fang <leofang@bnl.gov>

* ENH: set correct __module__ for objects in numpy's public APIStephan Hoyer2018-11-131-2/+3
| | | | | | | | | | | | | Fixes GH-12271 Tests verify that everything in ``dir(numpy)`` either has ``__module__`` set to ``'numpy'``, or appears in an explicit whitelist of undocumented functions and exported bulitins. These should eventually be documented or removed. I also identified a handful of functions for which I had accidentally not setup dispatch for with ``__array_function__`` before, because they were listed under "ndarray methods" in ``_add_newdocs.py``. I guess that should be a lesson in trusting code comments :).
