WitrynaIn mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a scalar function on Euclidean space.It is usually denoted by the symbols , (where is the nabla operator), or .In a Cartesian coordinate system, the Laplacian is given by the sum of second partial derivatives of the function with respect … WitrynaCartesian coordinates, specified as scalars, vectors, matrices, or multidimensional arrays. x, y, and z must be the same size, or have sizes that are compatible (for example, x is an M-by-N matrix, y is a scalar, and z is a scalar or 1-by-N row vector). dustin may baseball player
