An approach based on the pseudospectral method for fractional telegraph equations[J]. AIMS Mathematics, 2023, 8(12): 29221-29238. doi: 10.3934/math.2023149610.3934/math.20231496https://hdl.handle.net/10433/19490We aim to implement the pseudospectral method on fractional Telegraph equation. To implement this method, Chebyshev cardinal functions (CCFs) are considered bases. Introducing a matrix representation of the Caputo fractional derivative (CFD) via an indirect method and applying it via the pseudospectral method helps to reduce the desired problem to a system of algebraic equations. The proposed method is an effective and accurate numerical method such that its implementation is easy. Some examples are provided to confirm convergence analysis, effectiveness and accuracy.application/pdfenAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Convergence analysisChebyshev cardinal functionsFractional Telegraph equationPseudospectral methodjournal articleopen access
