Abstract In this paper, a necessary and sufficient condition for constructing a shape preserving C1 cubic interpolation spline function is obtained, and two new simple algorithms. one for directly constructing shape preserving C1 cubic interpolation spline functions, and the other for constructing shape preserving C1 piecewise cubic interpolation functions by insetting some new nodes, are given.
