Laplacian in 1D, 2D, or 3D软件

Sparse (1-3)D Laplacian on a rectangular grid with exact eigenpairs.

软件应用简介

Example, compute everything for 3D negative Laplacian with mixed boundary conditions: 

[lambda,V,A] = laplacian([100,45,55],{‘DD’ ‘NN’ ‘P’}, 20); 

Compute only the eigenvalues: 

lambda = laplacian([100,45,55],{‘DD’ ‘NN’ ‘P’}, 20); 

Compute the matrix only: 

[~,~,A] = laplacian([100,45,55],{‘DD’ ‘NN’ ‘P’});
