摘要
本文利用差分格式将n阶变系数线性常微分方程转化为n阶变系数线性差分方程,由文[2]我们即可得到n阶变系数线性常微分方程的一种差分近似解。
By use of difference type,We transform the n-th order linear ordinary differential equation with variable coefficients into the n-th order linear difference equation with variable cofficientS, thus,we got the difference approximation solution of the n-th order linear ordinary differential eqttation with variable coefficients.
