An extended differential quadrature method is used to compute nonlinear partial differential equations for tbree-dimensional laminar boundary layer now in this paPer. The key technique to differential quadrature, which is used in determining weighting coefficients for discretization of any order partial derivative, is investigated. The method of computing different weighting coefficients is presented. Three dimensional boundary layer equations are discretized by the differential quadrature method, and relative formula is obtained. The resulting scheme is applied to the computation of examples, which shows that the differential quadrature method can achieve rather high accurate solution using much less grid points than those of other methods, suck as finite difference and finite element methods.
