Resumen:
We show that Prony?s method provides the full solution to the nonlinear equations of theconnected-moments expansion (CMX). Knowledge of all the parameters in the CMX ansatz isuseful for the analysis of the convergence properties of the approach. Prony?s method may alsobe suitable for the calculation of the correlation function for simple quantum-mechanicalmodels.
