Numerical Method for Space- and Time-Fractional Telegraph Equation with Generalized Lagrange Multipliers

In the present article, we applied a novel methodology for solving time-fractional and space-fractional telegraph equation with the help of new Lagrange multiplier. We compare the analytic solution and numerical solution obtained by iterative method using graphs, find analytic solution and plotted absolute error for different value of fractional order that proves obtained numerical solution by employed technique converges very fast to the analytic solution
