Transform ukernel.

Construction
------------

.. index:: pair: function; transform
.. _doxid-structdnnl_1_1ukernel_1_1transform_1a7c2caec8844bba799da0a2b19c1a6477:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	transform()

Default constructor. Produces an empty object.

.. index:: pair: function; transform

		bool allow_empty = false
		)

Constructs a transform object.



.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- K

		- Dimension K.

	*
		- N

		- Dimension N.

	*
		- in_pack_type

		- Input packing type. Must be one of ``:ref:`pack_type::no_trans <doxid-group__dnnl__api__ukernel__utils_1gga241c23d0afdf43a79d51ef701a9f7c54a76659c0424cb9f2555bc14e7d947db13>```, or ``:ref:`pack_type::trans <doxid-group__dnnl__api__ukernel__utils_1gga241c23d0afdf43a79d51ef701a9f7c54a4738019ef434f24099319565cd5185e5>```.

	*
		- in_ld

		- Input leading dimension.

	*
		- out_ld

		- Output leading dimension. Specifies a block by N dimension during data packing.

	*
		- in_dt

		- Input data type.

	*
		- out_dt

		- Output data type.

	*
		- allow_empty

		- A flag signifying whether construction is allowed to fail without throwing an exception. In this case an empty object will be produced. This flag is optional and defaults to false.
