: number of the zone in which the cost will be computed
Estimation
: value of linear interpolation by solving Laplace's equation
Value
cost computed by replacing values in zone by linear interpolation
Details
: function that returns the criterion COST by approximating the valeur in a point of the grid by
the linear interpolation (approximate solution of Laplace's equation. For more details see help of function
Transition_Zone_Near_Boundary, Transition_Zone_Far_Boundary or Extreme_Zone)
