returns whether symmetry is defined

Syntax

sym = symmetry(obj)

Description

sym = symmetry(obj) returns true if equivalent couplings are generated based on the crystal space group and all matrices (interaction, anisotropy and g-tensor) are transformed according to the symmetry operators. If false, equivalent couplings are generated based on bond length, equivalent matrices won’t be transformed (all identical).

To switch between the two behaviour use spinw.gencoupling with the forceNoSym parameter set to true. To remove all symmetry operators use spinw.nosym.
