Solving linear integro-differential equations system by using rationalized Haar functions method

摘要

In this paper, we use rationalized Haar functions to estimate the solution of linear integro-differential equations system. Properties of rationalized Haar functions are first presented, and the operational matrix of the product of two rationalized Haar functions vector is utilized to reduce the computation of linear integro-differential equations system to some algebraic equations. By using numerical examples we show our estimation have a good degree of accuracy.
