determines point group symmetry of a space group at a given position pOp = SW_POINTSYM(sym, r) It determines point group symmetry in an arbitrary position in the unit cell in any space group. Returns all the generators of the point group. Input: sym Line index in the symmetry.dat file or string of the symmetry operators or a cell containing the output of sw_gencoord(). r Position in the unit cell, dimensions are [3 1]. Output: pOp Point group operators, dimensions are [3 3 npOp], these operators act on the relative atomic positions (they are in the lattice coordinate system). To convert them to Cartesian coordinate system, use: R = A*pOp(:,:,ii)*inv(A) Where A is a 3x3 matrix, containing the basis vectors of the lattice as column vectors. See also SW_GENATPOS, SW_GENCOORD, SW_GENSYM, SW_BASISMAT.
