  Recently, Bert, Wang and Striz [1, 2] applied the differential quadrature
(DQ) and harmonic differential quadrature (HDQ) methods to analyze static and
dynamic behaviors of anisotropic plates. Their studies showed that the methods
were conceptually simple and computationally efficient in comparison to other
numerical techniques. Based on some recent work by the present author [3, 4],
the purpose of this note is to further simplify the formulation effort and
improve computing efficiency in applying the DQ and HDQ methods for these
cases.
