In this note, we solve the dynamical sampling problem for a class of shift-preserving operators L:V→V acting on a finitely generated shift-invariant space V. We find conditions on L and a finite set of functions of V so that the iterations of the operator L on the functions produce a frame generator set of V. This means that the integer translations of the generators form a frame of V.Fil: Aguilera Aguilera, Alejandra Patricia. Consejo Nacional de Investigaciones Científicas y Técnicas.
