Abstract
The global methods of generalized differential quadrature (GDQ) and generalized integral
quadrature (GIQ) for solutions of partial differential and integral equations are presented in this paper. These methods approximate the derivatives and integrals by a linear combination of all the functional values in the overall domain, where the weighting coefficients can be readily identified. The error estimations of GDQ and GIQ have also been analysed. Application of GDQ and GIQ to solve boundary layer equations demonstrated that accurate numerical results can be obtained using just a few grid points
