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.
