* Mark `d` argument to fftfreq and rfftfreq as optional in type stubs.Peter Hawkins2023-03-031-4/+4
| | | | The type stubs incorrectly mark this argument as mandatory.
* MAINT: Simplify temporary dimensions by using static arraySebastian Berg2023-02-211-4/+2
| | | | | Using maxdims for this is the typical pattern in NumPy and avoids the malloc call.

* BLD: enable building NumPy with MesonRalf Gommers2022-11-251-0/+33
| | | | | | | | | | | | | | | | | | | This enables building with NumPy on Linux and macOS. Windows support should be complete to, but is untested as of now and may need a few tweaks. This contains: - A set of `meson.build` files and related code generation script tweaks, header templates, etc. - One CI job on Linux - Basic docs on using Meson to build NumPy (not yet integrated in the html docs, it's too early for that - this is for early adopters right now). The build should be complete, with the major exception of SIMD support. The full test suite passes. See gh-22546 for the tracking issue with detailed notes on the plan for switching NumPy to Meson as its build system. Co-authored-by: Stefan van der Walt <stefanv@berkeley.edu>

* STY: Small cleanups of includes in *.c files.Charles Harris2021-09-031-1/+2
| | | | | | | | | | | | | | | | This puts the following numpy defines at the top of the files before the includes. define NPY_NO_DEPRECATED_API NPY_API_VERSION define _MULTIARRAYMODULE define _UMATHMODULE There are also minor cleanups of <...> vs "..." include styles together with a small fix to the .clang-format file to include "pymem.h" among the Python supplied headers. Further cleanups will follow if clang-format is used on the files but that is not done here.

* DOC: Update some plotting code to current Matplotlib idiomsTim Hoffmann2021-03-211-3/+5
| | | | | | | | | - 3D Axes are created via add_subplot(projection='3d') - There is now a `stairs()` function that's specifically designed for showing histogram curves - Labels should be passed as keyword arguments to the plot functions instead of to `legend()`, which reduces the risk of mixing them up. - ensure equal axis scaling in the meshgrid example

* 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 calculation
| * 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>
