_cell.metric_tensor

Definition:

   
     The direct space (covariant) metric tensor used to transform
     vectors and coordinates from real (direct) to reciprocal space.

Type: Real

Values appear in Matrix context.

Dimension: [3,3]

Evaluation method:

     with c  as  cell
 
           _cell.metric_tensor = [[ c.vector_a*c.vector_a, c.vector_a*c.vector_b, c.vector_a*c.vector_c ],
                                  [ c.vector_b*c.vector_a, c.vector_b*c.vector_b, c.vector_b*c.vector_c ],
                                  [ c.vector_c*c.vector_a, c.vector_c*c.vector_b, c.vector_c*c.vector_c ]]
