pydda.cost_functions.calculate_smoothness_cost(u, v, w, dx, dy, dz, Cx=1e-05, Cy=1e-05, Cz=1e-05)

Calculates the smoothness cost function by taking the Laplacian of the wind field. All arrays in the given lists must have the same dimensions and represent the same spatial coordinates. :Parameters: * u (Float array) – Float array with u component of wind field

• v (Float array) – Float array with v component of wind field

• w (Float array) – Float array with w component of wind field

• Cx (float) – Constant controlling smoothness in x-direction

• Cy (float) – Constant controlling smoothness in y-direction

• Cz (float) – Constant controlling smoothness in z-direction

Returns:

Js (float) – value of smoothness cost function
