针对线性的RLW方程提出了一种特征-块中心差分法,不但得到了近似解和解的一阶导数,还给出L2模的误差估计,并且数值实验结果与理论分析一致,说明了该方法的可行性和有效性.
A characteristic block-centered difference method is proposed for the linear RLW equation. We not only get the approximate solution and its first derivatives, but also give the L^2 norm error estimates,and numerical results consistent with the analysis of the theory which denmonstrates feasibility efficiency of the method.
