<p>
|
|
This example solves the 2-D Laplacian eigenvalue problem with zero boundary
|
|
conditions on an nxn grid. The number of unknowns is N=n^2. The standard
|
|
5-point stencil is used, and we solve for the interior nodes only.
|
|
<p>
|
|
We use the same matrix as in Examples 3 and 5. The eigensolver is LOBPCG with
|
|
AMG preconditioner.
