Abstract

Some numerical algorithms for computing eigenvalues of nonsymmetric matrix
with high accuracy have been recently designed based on the discrete hungry Toda equation
and the discrete Lotka-Volterra system which are known as the discrete integrable systems
of hungry type. In this paper, not only the process for formulating these algorithms but
also the results concerning asymptotic analysis through the center manifold theory, mixed
error analysis in
oating point arithmetic and shift of origin for accelerating convergence
are shortly explained. Backlund transformations between discrete integrable systems of
hungry type are also shown.
