There are a couple of purposes in this paper: to study a problem of approximation with exponential functions and to show its relevance for the economic science. We present results that completely solve the problem of the best approximation by means o

A new package for nonlinear least squares fitting is introduced in this paper. This package implements a recently developed algorithm that, for certain types of nonlinear curve fitting, reduces the number of nonlinear parameters to be fitted. One not

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.

A series of novel and previously published organoantimony compounds (RnSbX3−n, X = Cl, Br; R = o-tolyl, 2,6-xylyl, 1-naphthyl, and 9-anthracenyl), were synthesized and characterized. In addition, single-crystal X-ray diffraction was employed to elu
