-The main purpose of the symmetry-representation code is to provide classes which describe these symmetry operations and their representations. These can then be used by other codes, such as `TBmodels <http://z2pack.ethz.ch/tbmodels>`_ or `kdotp-symmetry <http://z2pack.ethz.ch/kdotp-symmetry>`_.

 Within symmetry-representation, symmetry operations are described using the :class:`.SymmetryOperation` class. This class has the following parameters:

-The ``numeric`` flag determines whether ``numpy`` arrays (``True``) or ``sympy`` matrices (``False``) are created. The former are suited for use with the `TBmodels <http://z2pack.ethz.ch/tbmodels>`_ code, while the latter should be used for `kdotp-symmetry <http://z2pack.ethz.ch/kdotp-symmetry>`_.

 Additionally, there is a special helper function to create a representation of the time-reversal symmetry operation:
