| Abstract: | The paper introduces a kind of differentiable fractal interpolation function,discusses its generating mechanismas well as the sufficient condition that generates its IFS.On the basis of the previous process,the definition of SFIF is given and some convergence properties are discussed.The interpolation of the spline fractal interpolation function provides a newmethod for the subject of computer graph and vision simulation.The significance of SFIF exists not only in the traditional spline theory but also in the engineering application. |
