Stability Analysis of Some Fractional Differential Equations by Special type of Spline Function

Journal of Zankoy Sulaimani - Part A, 2017
One fractional spline interpolation is presented in this paper for the solution fractional initial value problems that is with spline interpolation as a new class depended on class splines as a method to approximate the exact solution of such problem. Error bounds were discussed as the presented spline function.
