Haar Wavelet Collocation Method for Solving the Telegraph Equation with Variable Coefficients

摘要

The telegraph equation is one of the important equations of mathematical physics. In the current work, we implement the Haar wavelet collocation method (HWCM) to find numerical solution of one-dimensional telegraph equation with variable coefficients. Two illustrative numerical examples are given to show the stability and accuracy of the present method. The obtained numerical results are found to be in good agreement with known analytical solutions and also with earlier studies.
