For the case of a finite-dimensional graph (having a finite number of edges and vertices), the discrete Laplace operator is more commonly called the Laplacian matrix. The discrete Laplace operator occurs in physics problems such as the Ising model and loop quantum gravity, as well as in the study of discrete dynamical systems. It is also used in numerical analysis as a stand-in for the continuous Laplace operator. Common applications include image processing, where it is known as the Laplace filter, and in machine learning for clustering and semi-supervised learning on neighborhood graphs.

Based on the particle velocities. Finally, MSHAKE computes corrections on the constraint forces, achieving better convergence. A final modification is the P-SHAKE algorithm for rigid or semi-rigid molecules. PSHAKE computes and updates a pre-conditioner which is applied to the constraint gradients before the SHAKE iteration, causing the Jacobian to become diagonal or strongly diagonally dominant. The thus de-coupled constraints converge much faster (quadratically as opposed to linearly) at a cost of .

In edge detection and motion estimation applications. The discrete Laplacian is defined as the sum of the second derivatives Laplace operator#Coordinate expressions and calculated as sum of differences over the nearest neighbours of the central pixel. Implementation in Image Processing For one, two and three dimensional signals, the discrete laplacian can be given as convolution with the following kernels: 1D-Filter: 2D-Filter: or, including the diagonals: 2D-Filter: 3D-Filter: is given by: first plane = ; second plane = ; third plane = These kernels are deduced by using discrete differential quotients.
