_cell.reciprocal_orthogonal_matrix

Name:
_cell.reciprocal_orthogonal_matrix

Definition:

   
    Orthogonal matrix of the reciprocal space. The matrix may be
    used to transform the non-orthogonal vector h = (h,k,l) into
    the orthogonal indices p = (p,q,r):

                M h = p.

Type: Real

Values appear in Matrix context.

Dimension: [3,3]

Units: reciprocal_angstroms

Evaluation method:

    _cell.reciprocal_orthogonal_matrix  =  Inverse(

                           Transpose( _cell.orthogonal_matrix ))
