Description

This code computes a (1-3)D sparse Laplacian matrix on a rectangular finite difference or finite element methods, as well as the eigenvalues and eigenvetors computed from an exact formula.

Works for combinations of different boundary conditions.

See help file and report for more information.

Makes use of Kronecker sums of 1D Laplacians. For more information on tensor sums, see
