摘要: A numerical method based on exponential spline and finite difference approximations is developed to solve the generalized Burgers'-Fisher equation. The error analysis, stability convergence properties of are studied via energy method. shown be unconditionally stable accurate orders 𝒪(k + kh + h 2) 4). Some test problems given demonstrate applicability purposed numerically. Numerical results verify theoretical behaviour properties. main superiority presented scheme its simplicity in comparison with existing well-known methods.
