WebA very popular second order operator is the Laplacian operator. The Laplacian of a function f ( x, y ), denoted by , is defined by: Once more we can use discrete difference approximations to estimate the derivatives and represent the Laplacian operator with the convolution mask shown in Fig 25 . Fig. 25 Laplacian operator convolution mask. WebThe complex-step method is a clever way of obtaining a numerical approx-imation to the first derivative of a function, avoiding the round-off error that plagues standard finite …
