SymRep (int=0)
SymRep (const SymmetryOperation &)
operator SymmetryOperation () const
Cast to a SymmetryOperation. double trace () const
returns the trace of the transformation matrix void set_dim (int i)
set the dimension of d double * operator[] (int i)
returns the i'th row of the transformation matrix const double * operator[] (int i) const
const version of the above double & operator() (int i, int j)
returns a reference to the (i,j)th element of the transformation matrix double operator() (int i, int j) const
const version of double& operator()(int i, int j) void zero ()
zero out the symop SymRep operate (const SymRep &r) const
This operates on this with r (i.e. return r * this). SymRep transform (const SymRep &r) const
This performs the transform r * this * r~. void unit ()
