چکیده
|
In this paper, we propose direct methods to solve linear delay differential equations (lddes) based on vector forms of block-pulse functions (bpfs) and triangular functions (tfs). operational matrix of integration of bpfs and tfs is applied to transform ldde to a linear system of algebraic equations. furthermore, some numerical examples are presented to indicate the reliability and the accuracy of these methods. convergence analysis of the present method has been discussed, too.
