摘要：

The aim of this paper is to describe an algorithm for computing co-monotone and/or co-convex splines of degree m and deficiency m-k at the knots (0 less than k less than m minus k), which are interpolant or osculatory to a given set of data. The method is based upon some existence properties recently developed. Graphical examples and a listing of the FORTRAN code SPISP1 are given. This work is application to computer aided design.
