摘要：

The analytical Lanczos method is a simple method to calculate the eigenstates of quantum-mechanical Hamiltonians of systems with several degrees of freedom. High precision eigenvalues and eigenfunctions are obtained for the anharmonic oscillator, and for two, three and four coupled anharmonic oscillators, by diagonalizing small tridiagonal matrices.
