| Abstract: | Error estimation for the differential quadrature (DQ)with various sets of grid spacing is presented. A general formula is given to compute the weighting coefficients directly. It is found that the maximum error of the Do method with roots of Chebyshev polynomials including two end POints (-1 and + 1 ) is the smallest among the several sets of grid spacing investigated herein. |
