摘要
This paper presents a computational method based on least squares method and block pulse functions for solving Ito-Volterra integral equation. The Ito-Volterra integral equation is converted to a linear system of algebraic equations by the least squares method on the block pulse functions. The error analysis of the proposed method is investigated by providing theorems. Numerical examples show the accuracy and reliability of the presented method. The numerical results confirm that the presented method is more accurate than the block pulse functions operational matrix method.
