Public Methods

 SymmetryOperation ()
 SymmetryOperation (const SymmetryOperation &)
 ~SymmetryOperation ()
double trace () const
 returns the trace of the transformation matrix.

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 the above.

void zero ()
