摘要 对一类对流扩散方程的周期初值问题提出了一种新的数值求解方法—特征拟谱方法,此方法既有特征方法的优点,又有拟谱方法的优点.证明了该方法的收敛性,并给出了最优阶误差估计. In this paper, a new numerical method-characteristic pseudospectral method for solving a class of convection diffusion problems is proposed,which combines the advantages of the character method and of the pseudospectral method, the convegence is proved and the optimal order error estimate is given.
