| Abstract : | A piecewise rational cubic spline has been introduced to preserve the shape Of the data when it is positive. The spline representation is interpolatory and applicable to the scalar valued data. The shape parameters, in the description of the rational cubic, have been constrained in such a way that they control the shape of the curve to avoid any noise As far as visual smoothness is concerned the curve scheme under discussion is C-1., |
