Discrete Schrödinger operator; Discrete Green's function; Discrete laplace operator; Discrete Schrodinger operator; Discrete Schroedinger operator; Discrete Laplacian operator; Laplace filter
In mathematics, the discrete Laplace operator is an analog of the continuous Laplace operator, defined so that it has meaning on a graph or a discrete grid. 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.
