_atom_sites_fract_transform.mat_13

Definition:

   
     Matrix used to transform Cartesian coordinates in the ATOM_SITE
     category to fractional coordinates. The axial alignments of this
     transformation are described in _atom_sites_fract_transform.axes.
     The 3x1 translation is defined in _atom_sites_fract_transform.vector.

   x'                  |11 12 13|     x                  | 1 |
     ( y' )fractional = mat|21 22 23| * ( y )Cartesian +  vec| 2 |
   z'                  |31 32 33|     z                  | 3 |

     The default transformation matrix uses Rollet's axial
     assignments with cell vectors a,b,c aligned with orthogonal
     axes X,Y,Z so that c||Z and b in plane YZ.
