一种求解带有第三类边界条件的Laplace方程的九点差分格式,它是通过坐标轴旋转结合传统的五点差格式得到的,讨论了这种差分格式的误差估计.“,”In this paper,a new method called nine points difference schema for solving Laplace equation with the third type boundary value conditions is presented.It is obtained by the rotation of the coordinate and combined with the traditional five finite difference method.Error estimation of this method are discussed.
