DOC: Update some plotting code to current Matplotlib idioms

2021-03-21T21:32:52+00:00

- 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.

2020-12-19T03:56:37+00:00

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.

DOC: update rfft2/irfft2 examples.

2020-08-18T06:16:50+00:00

Update rfft2 example to conform to fft2 example and switch the irfft2
example to illustrate round-tripping.

DOC: added examples for rfft2 and irfft2 docstring

ENH: add `norm=forward,backward` to numpy.fft functions (#16476)

2020-07-12T19:43:30+00:00

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

Add missing closing brackets, script to generate the list in the PR gh-16051.

MAINT: Pull identical line out of conditional.

2020-02-23T04:26:11+00:00

There was an identical statement in both possible branches of
a conditional.

Moved statement out of conditional to eliminate one
repititious LOC

MAINT: Remove unnecessary 'from future import ...' statements

2020-01-03T15:48:11+00:00

As numpy is Python 3 only, these import statements are now unnecessary
and don't alter runtime behavior.
