摘要:
讨论了变系数微分代数方程的数值解.首先给出变系数微分代数方程的系数矩阵Drazin逆的求法,然后研究其差分格式上的数值解,最后利用Drazin逆的方法和隐式RK方法对一类变系数微分代数方程进行了研究,并给出了相应的数值试验,结果表明Drazin逆的求解效果较好,但求解过程比较复杂.
Abstract:
The rationalized Haar functions are used to solve the solution of fractional order Fredholm integral equation of the second kind.The integral equation can be reduced to a system of algebraic equations by using rationalized Haar wavelet and collection method.Finally,the numerical solution of fractional integral equation with exact solution and the numerical solutions using Haar wavelet are compared.The result shows that the algorithm has high accuracy.
