The present study investigates the Haar-Sinc collocation method for the solution of the hyperbolic partial telegraph equations. The\nadvantages of this technique are that not only is the convergence rate of Sinc approximation exponential but the computational\nspeed also is high due to the use of the Haar operational matrices. This technique is used to convert the problem to the solution\nof linear algebraic equations via expanding the required approximation based on the elements of Sinc functions in space and Haar\nfunctions in time with unknown coefficients. To analyze the efficiency, precision, and performance of the proposed method, we\npresented four examples through which our claim was confirmed.
