摘要
求解微分方程初值问题是小波分析在数学上的一个重要应用。在已有的利用H aar小波求解微分方程方法的基础上,对求解R iccati方程初值问题的离散化过程进行了改进,减小了运算量。数值实验表明,该方法在数值上精度略好于文献中利用H aar小波求解微分方程的方法。
One application of wavelets on mathematics is to solve the initial value of differential equation. The way to discrete Riccati equation has been modified based on the method to solve the initial value of differential equation using Haar wavelet in discussion. Our method has less operation. The numerical value test shows that our method has advantages in terms of precision over other methods referred to in this paper.
