_atom_sites_Cartn_transform.matrix

Definition:

   
     Matrix used to transform fractional coordinates in the ATOM_SITE
     category to Cartesian  coordinates. The axial alignments of this
     transformation are described in _atom_sites_Cartn_transform.axes.
     The 3 x 1 translation is defined in _atom_sites_Cartn_transform.vector.
 
   x'                   |11 12 13|     x                  | 1 |
     ( y' ) Cartesian   =   |21 22 23| * ( y ) fractional  + v| 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.

Type: Real

Values appear in Matrix context.

Dimension: [3,3]

Evaluation method:

     With a as atom_sites_Cartn_transform
 
     _atom_sites_Cartn_transform.matrix = [[a.mat_11, a.mat_12, a.mat_13],
                                           [a.mat_21, a.mat_22, a.mat_23],
                                           [a.mat_31, a.mat_32, a.mat_33]]
