چكيده فارسي :
In this paper, the telegraph equation is solved numerically by
cubic B-spline quasi-interpolation. We obtain the numerical scheme, by
using the derivative of the quasi-interpolation to approximate the spatial
derivative of the dependent variable and a low order forward difference to
approximate the temporal derivative of the dependent variable. The results
of numerical experiments are presented, and are compared with analytical
solutions by calculating errors L2 and L1 norms
