Abstract

In this paper, we give some theoretical discussion on the local algorithm of the two level method, which is shown to be efficient in data experiments. Under the assumption of scale separation, we show that the errors between the local optimal solution and the real intrinsic mode function (IMF) in the subintervals are still
