Report

Chebyshev approximation of exponential data

Autor: Fernández, Mariano Rodríguez-Arias, Sánchez, Javier Cabello, Torvisco, Juan Antonio Fernández

In this paper we present an algorithm to fit data via exponentials when the error is measured using the max-norm. We prove the necesssary results to show that the algorithm will converge to the best approximation no matter the dataset.

Report

A New Algorithm to Fit Exponential Decays

Autor: Torvisco, Juan Antonio Fernández, Fernández, Mariano Rodríguez-Arias, Sánchez, Javier Cabello

This paper deals with some nonlinear problems which exponential and biexponential decays are involved in. A proof of the quasiconvexity of the error function in some of these problems of optimization is presented. This proof is restricted to fitting
