sc::SymmetryOperation(3) MPQC sc::SymmetryOperation(3) NAME sc::SymmetryOperation - The SymmetryOperation class provides a 3 by 3 ma- trix representation of a symmetry operation, such as a rotation or reflec- tion. SYNOPSIS #include <pointgrp.h> Public Member Functions SymmetryOperation (const 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 () zero out the symop SymmetryOperation operate (const SymmetryOperation &r) const This operates on this with r (i.e. return r * this). SymmetryOperation transform (const SymmetryOperation &r) const This performs the transform r * this * r~. void unit () Set equal to a unit matrix. void E () Set equal to E. void i () Set equal to an inversion. void sigma_h () Set equal to reflection in xy plane. void sigma_xz () Set equal to reflection in xz plane. void sigma_yz () Set equal to reflection in yz plane. void rotation (int n) Set equal to a clockwise rotation by 2pi/n. void rotation (double theta) void c2_x () Set equal to C2 about the x axis. void c2_y () Set equal to C2 about the x axis. void transpose () void print (std::ostream &=ExEnv::out0()) const print the matrix Detailed Description The SymmetryOperation class provides a 3 by 3 matrix representation of a symmetry operation, such as a rotation or reflection.
