Differential Quadrature Solution of Hyperbolic Telegraph Equation [PDF]

open access: yesJournal of Applied Mathematics, 2012
Differential quadrature method (DQM) is proposed for the numerical solution of one‐ and two‐space dimensional hyperbolic telegraph equation subject to appropriate initial and boundary conditions. Both polynomial‐based differential quadrature (PDQ) and Fourier‐based differential quadrature (FDQ) are used in space directions while PDQ is made use of in ...
