| الوصف: | This paper describes an algorithm for computing best l 1 , l 2 and l ∞ approximations to discrete data, by functions of several parameters which depend nonlinearly on just one of these parameters. Such functions (e.g. a 1 + a 2 e cx , a 1 + a 2 sin cx, ( a 1 + a 2 x )/(1 + cx )) often occur in practice, and a numerical study confirms that it is feasible to compute best approximations in any of the above norms when using these functions. Some remarks on the theory of best l 1 approximations by these functions are included. |
