A Digital-Discrete Method For Smooth-Continuous Data Reconstruction

Li Chen

A systematic digital-discrete method for obtaining continuous functions with smoothness to a certain order (C^(n)) from sample data is designed. This method is based on gradually v…

Smoothness and Smooth Extensions (I): Generalization of MWK Functions and Gradually Varied Functions

Li Chen

A mathematical smooth function means that the function has continuous derivatives to a certain degree C(k). We call it a k-smooth function or a smooth function if k can grow infini…
