Laplacian

Generate Gaussian or Laplacian pyramids, or reconstruct an image from a pyramid. Contains a demo script doing image blending using pyramids. The function is more convenient to use than the Matlab function impyramid.

The code computes the exact eigenpairs of (1-3)D negative Laplacian on a rectangular finite-difference grid for combinations of Dirichlet, Neumann, and Periodic boundary conditions using explicit formulas fromhttp://en.wikipedia.org/wiki/Eigenvalues_a...cond_derivativeThe code can also compute...

MESH_LAPLACIAN: Laplacian of irregular triangular meshUseage: [lap,edge] = mesh_laplacian(vertex,face)Returns 'lap', the Laplacian (2nd spatial derivative) of an irregular triangular mesh, and 'edge', the linear distances between vertices of 'face'. 'lap' and 'edge' are square,...
