摘要
对一类两点边值常微分方程给出两种差分算法,一种算法具有一阶精度,另一种算法具有二阶精度,两种算法均得到的差分格式的系数矩阵为三对角矩阵,可用追赶法求解。并举数值例子来验证两种算法的精度。
Two difference methods are presented in this article for solving differential equations with boundary.One method is first-order accuracy,another is second-order accuracy.Coefficient matrix is tridiagonal matrix.Thomas method is used to get the solutions.At the same time,numerical example is presented to show the difference methods’accuracy.
