Chebyshev approximation of exponential data
Mariano Rodríguez-Arias Fernández, Javier Cabello Sánchez, Juan Antonio Fernández Torvisco
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 co…
