Abstract: | A full multigrid scheme was used in computing some eigenvalues of the Laplace eigenvalue problem with the Dirichlet boundary condition. We get a system of algebraic equations with an aid of finite difference method and apply subspace iteration method to the system to compute first some eigenvalues. The result shows that this is very effective in calculating some eigenvalues of this problem. |
