##########################

*Transform Functions*

Type: ``bool``

Help
====

.. code-block:: none

    This option enables the Transform Functions, which support the
    following transformations:

    * Real Fast Fourier Transform (RFFT)
    * Complex Fast Fourier Transform (CFFT)
    * Type IV Discrete Cosine Transform (DCT4)

Direct dependencies
===================

\ :kconfig:`CMSIS_DSP <CONFIG_CMSIS_DSP>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

No defaults. Implicitly defaults to ``n``.
