* MAINT: Stop using non-tuple indices internallyEric Wieser2018-02-161-2/+2
| | | | | | By not using this type of indexing, it becomes easier for subclasses to override indexing in a way that works correctly with numpy functions. These locations were found by deprecating the behavior in question, which is deliberately not part of this commit
* BUG: correct norm='ortho' scaling for rfft when n != NoneGregory R. Lee2017-01-041-1/+3

* DOC: Correct documentation of hfft/ihfft.Charles Harris2016-11-041-28/+33
| | | | | | | | | Corrections to #7492. Correct the examples in the notes specifying the output length for the hfft. Also clean up the documentation a bit. [ci skip]

* BUG: Fix race condition with new FFT cacheLion Krischer2016-06-071-5/+12
| | | | | | There is now a lock around cache accesses ensuring thread safety. The size of a cache entry is now also calculated by summing over all arrays in the list.
* ENH: Changing FFT cache to a bounded LRU cacheLion Krischer2016-06-061-2/+3
| | | | | | | | 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 Harris2013-08-181-9/+9
| | | | | | | 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.
* STY: Giant whitespace cleanup.Charles Harris2013-08-181-6/+6
| | | | Now is as good a time as any with open PR's at a low.
* 2to3: Apply `print` fixer.Charles Harris2013-04-061-1/+1
| | | | | | | Add `print_function` to all `from __future__ import ...` statements and use the python3 print function syntax everywhere. Closes #3078.
* 2to3: Use absolute imports.Charles Harris2013-03-281-2/+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: Replace xrange by range and use list(range(...)) where neededCharles Harris2013-03-271-2/+2
| | | | | | | | | | | | | | | In python3 range is an iterator and `xrange` has been removed. This has two consequence for code: 1) Where a list is needed `list(range(...))` must be used. 2) `xrange` must be replaced by `range` Both of these changes also work in python2 and this patch makes both. There are three places fixed that do not need it, but I left them in so that the result would be `xrange` clean. Closes #3092
* 2to3: Put `from __future__ import division in every python file.Charles Harris2013-03-011-0/+2
| | | | | | | | 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.
