SOLUTION OF MULTI-DELAY OF LINEAR INTEGRO-DIFFERENTIAL EQUATIONS USING WALSH FUNCTIONS

A matrix, called the delay operational matrix, is constructed from the Walsh matrix, this matrix, together with some matrices obtained from the delay operational matrix after performing right-shift operations, is used to solve the multi-delay linear integro-differential equations (Fredholm and Volterra). Examples are given to compare between the exact and the approximate solution that obtained by using this method.
