Toda Molecule Equation and Quotient-Difference Method
Kiyoshi Sogo · Journal of the Physical Society of Japan · 1993
The numerical algorithm for computing eigenvalues of a given matrix using the Toda molecule equation, suggested recently by Hirota, Tsujimoto and Imai, is shown to be equivalent to the quotient-difference method. This relation, convergence of the algorithm and extension to a much wider range of matrices are described.
