* ENH: add `norm=forward,backward` to numpy.fft functions (#16476)Chris Vavaliaris2020-07-121-15/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* MAINT: cleanup unused imports; avoid redefinition of importsMike Taves2020-02-062-2/+1
| | | | | | | * Cleanup unused imports (F401) of mostly standard Python modules, or some internal but unlikely referenced modules * Where internal imports are potentially used, mark with noqa * Avoid redefinition of imports (F811)

* MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-052-7/+7
| | | | | | | Inheriting from object was necessary for Python 2 compatibility to use new-style classes. In Python 3, this is unnecessary as there are no old-style classes. Dropping the object is more idiomatic Python.
* MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-032-3/+0
| | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

| | | | | | | | | | Relaxed test_fft_with_order for float32. Infinity norm round-off error of FFT is shown in G.U. Ramos, "Roundoff Error Analyss of the Fast Fourier Transform," Mathematics of Computation, vol. 25, no. 116, Oct. 1971, p. 757 to be bounded by sqrt(N)*K*eps.

* MAINT: Remove all uses of run_module_suite.Charles Harris2018-04-062-11/+2
| | | | | That function is nose specific and has not worked since `__init__` files were added to the tests directories.

* TST, MAINT: Add `__init__.py` files to tests directories.Charles Harris2017-08-061-0/+0
| | | | | | | | This allows pytest to run with duplicate test file names. Note that `python <path-to-test-file>` no longer works with this change, nor will a simple `pytest numpy`, because numpy is imported from the numpy repository. However, `python runtests.py` and `>>> numpy.test()` are still available.

* ENH: Changing FFT cache to a bounded LRU cacheLion Krischer2016-06-061-0/+87
| | | | | | | | Replaces the simple dictionary caches for the twiddle factors of numpy.fft to bounded LRU (least recently used) caches. The caches can thus no longer grow without bounds. See #7686.

* STY: Giant comma spacing fixup.Charles Harris2013-08-181-1/+1
| | | | | | | Run the 2to3 ws_comma fixer on *.py files. Some lines are now too long and will need to be broken at some point. OTOH, some lines were already too long and need to be broken at some point. Now seems as good a time as any to do this with open PRs at a minimum.
* 2to3: Apply `print` fixer.Charles Harris2013-04-062-2/+2
| | | | | | | Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.
* 2to3: Use absolute imports.Charles Harris2013-03-282-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new import `absolute_import` is added the `from __future__ import` statement and The 2to3 `import` fixer is run to make the imports compatible. There are several things that need to be dealt with to make this work. 1) Files meant to be run as scripts run in a different environment than files imported as part of a package, and so changes to those files need to be skipped. The affected script files are: * all setup.py files * numpy/core/code_generators/generate_umath.py * numpy/core/code_generators/generate_numpy_api.py * numpy/core/code_generators/generate_ufunc_api.py 2) Some imported modules are not available as they are created during the build process and consequently 2to3 is unable to handle them correctly. Files that import those modules need a bit of extra work. The affected files are: * core/__init__.py, * core/numeric.py, * core/_internal.py, * core/arrayprint.py, * core/fromnumeric.py, * numpy/__init__.py, * lib/npyio.py, * lib/function_base.py, * fft/fftpack.py, * random/__init__.py Closes #3172
* 2to3: Put `from __future__ import division in every python file.Charles Harris2013-03-011-2/+4
| | | | | | | | This should be harmless, as we already are division clean. However, placement of this import takes some care. In the future a script can be used to append new features without worry, at least until such time as it exceeds a single line. Having that ability will make it easier to deal with absolute imports and printing updates.

| | | | | | | | | | | Added numpy.testing.run_module_suite to simplify "if __name__ == '__main__'" boilerplate code in test modules. Removed numpy/testing/pkgtester.py since it just consisted of an import statement after porting SciPy r4424. Allow numpy.*.test() to accept the old keyword arguments (but issue a deprecation warning when old arguments are seen). numpy.*.test() returns a test result object as before. Fixed typo in distutils doc.
