| چکیده | ||
| The main objective of this work is to provide a high-order numerical method to solve a class of integro-differential equations. By multiplying some efficient factors and constructing an appropriate approximate function, as well as utilizing a numerical integration method with order $\gamma$, the above-mentioned problem can be simplified to a non-linear system of algebraic equations. Furthermore, we discuss the convergence analysis of the presented method, in detail, and demonstrate that it converges with order $\mathcal{O}(h^{3.5})$ in $L^2$-norm. Some test examples are provided to demonstrate that the claimed order of convergence is obtained. | ||
