_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 ))
Category:
cell
