摘要
This paper presents a numerical method based on the QR factorization method and the second kind Chebyshev wavelets for solving the Ito-Volterra integral equation. The Clenshaw-Curtis quadrature rule convertes the Ito-Volterra integral equation to a non-square linear system of equations, then the least squares solution is obtained by the QR factorization method. The convergence rate of the presented method is proven. Numerical results show the rate reliability and efficiency of the presented method.
