| Abstract: | Two stable numerical methods for constructing a real symmetric band matrix with halfbandwidth r+1 from the given eigenvalues of the r+1 greatest leading principal submatrices arepresented. The numerical methods, the Generalized Lanczos Method and the Givens Method aredescribed, and some numerical results are given. |
