Correntropy Based Divided Difference Filtering for the Positioning of Ships [PDF]
In this paper, robust first and second-order divided difference filtering algorithms based on correntropy are proposed, which not only retain the advantages of divided difference filters, but also exhibit robustness in the presence of non-Gaussian noises,

On Solutions of Holonomic Divided-Difference Equations on Nonuniform Lattices [PDF]
The main aim of this paper is the development of suitable bases that enable the direct series representation of orthogonal polynomial systems on nonuniform lattices (quadratic lattices of a discrete or a q-discrete variable). We present two bases of this

Divided differences of implicit functions [PDF]
Under general conditions, the equation g ( x , y ) = 0 g(x,y) = 0 implicitly defines y y locally as a function of x x . In this article, we express divided differences of y y in terms of bivariate divided differences of ...
