Die explizite und voliständige Lösung von zwei speziellen Anfgaben. ier linear en iiskreten Approximation

Abstract

The problem of linear discrete approximation in the πdimensional BUCLOEB space for the two casas of minization of the bum of absolute vadex of errors and a special choice of the grid points all solutions can be given explicitely as the convex hull of the basic solutions. For the two special approximation problems an estimate of absolute varities of errors is carried out and the optirnality of the plan of grid points is considered.
