Laplacian Operator (Or Laplace Operator)
Laplacian Operator (Or Laplace Operator) : The mathematical operator V2 = V - V (or sometimes written A) where V is the del-operator. In rectangular Cartesian coordinates, the Laplacian operator may be expanded in the form: v2=^ + *-+ JL. dx2 dy2 dz2. See: Laplace equation. N.B. Refer to source to verify equation(s)
