			Data allocation
			===============

			Most of GooseFEM's functions provided an interface to:

			1. Allocate output arrays: names start with a upper-case letter. For example:

			.. code-block:: cpp

			ue = GooseFEM::Vector::AsElement(disp);

			2. Directly write to output arrays, without allocation them and copying them, by taking a pointer the externally allocated array as the last input argument(s): names start with a lower-case letter. For example:

			.. code-block:: cpp

			GooseFEM::Vector::asElement(disp, ue);

			.. note::

			The Python API only option 1. Option 2 is only available in the C++ API.
