 .....(n layers)

 Weighting is usually defined as 1 if each layer's parameters are calculated by user or GUI program. <br>
However, if it is not equal to 1, all parameters such as <math>\Delta_1</math>  <math>\Delta_2</math>  <math>\Delta_3</math> a c <math>c_{11}</math> <math>c_{12}</math> <math>c_{13}</math> <math>c_{33}</math> <math>c_{44}</math> <math>c_{66}</math>  <math>D_1</math> <math>D_2</math> <math>D_3</math> <math>D_4</math> <math>D_5</math> <math>D_6</math> will be weighted by   <br>

  n_layer_parameters = Weighting(n_layer_parameters) + (1-Weighting)*last_layer_parameters  <br>
 For example, if we have 5 layers, and weighting of the second layer is 0.5, then  <br>
  <math>\Delta_{1} (2)</math> =<math>\Delta_{1} (2) *  Weighting_2  + \Delta_{1} (5) *  (1-Weighting_2)</math>
