Symmetrization of tensors

You can also use the code for any tensor and list of symmetries, provided that you define how the tensor transforms under the symmetries. For this, the function symmetr.symmetrize.symmetr() function is used.

This takes as an input:

• “syms”: a list of symmetries, which can be in principle anything and is not restricted to the symmetr.symmetry.Symmetry class

• “X”: the symbolic tensor represented by the symmetr.tensors.Tensor class

• “trans_func”: function that transforms the tensor X by symmetry. It must work like this:

  X_trans = trans_func(X,sym,params)

• “params”: parameters to be sent to the trans_func.
