本文首先构造了第二类Chebyshev小波。在此基础上,提出了一种基于第二类Chebyshev小波的求解一类分数阶非线性Fredholm积分微分方程的计算方法。推导了第二类Chebyshev小波分数次积分运算矩阵,并将其转化为代数方程组。该方法的应用程序和所获得的结果进行了比较与现有的公开文献。此外,与已知的技术相比,该方法表明,本方法是更有效,更准确。
In this paper, we first construct the second kind Chebyshev wavelet. Then we present a computational method based on the second kind Chebyshev wavelet for solving a class of nonlinear Fredholm integro-differential equations of fractional order. The second kind Chebyshev wavelet operational matrix of fractional integration is derived and used to transform the equation to a system of algebraic equations. The method is illustrated by applications and the results obtained are compared with the existing ones in open literature. Moreover, comparing the methodology with the known technique shows that the present approach is more efficient and more accurate.
