KokkosFFT::fft
--------------

.. doxygenfunction:: KokkosFFT::fft(const ExecutionSpace& exec_space, const InViewType& in, const OutViewType& out, KokkosFFT::Normalization, int axis, std::optional<std::size_t> n)

.. note::

   For the real input, we internally convert it to complex and perform ``fft`` on it.

Examples
========

.. literalinclude:: ../../../examples/docs/standard/docs_fft.cpp
  :language: c++
  :linenos:
  :lines: 5-

Expected output:

.. code::

 (10,0) (-2,2) (-2,0) (-2,-2)
