Construction of Compact Finite Difference Schemes by Classic Differential Quadrature
Applied Sciences, 2017 Using classic differential quadrature formulae and uniform grids, this paper systematically constructs a variety of high-order finite difference schemes, and some of these schemes are consistent with the so-called boundary value methods.

Differential Quadrature Element Analysis Using Extended Differential Quadrature
Computers and Mathematics With Applications, 2000 In the extended differential quadrature, a (partial) derivative of a function at a point is expressed by a weighted sum of the values of the function and/or its derivatives at all grid points. Several sample problems with 1, 2, and 3 coordinates are sketched. Numerical results are presented too.
