Convex interval interpolation with cubic splines
The problem of convex interpolation with cubic splines (one-dimensional case) is considered in the situation of interval-valued function data. A necessary and sufficient condition is formulated for the solvability of the problem. On the basis of this condition an effective algorithm is proposed for the construction of the solution set. The algorithm uses a general method for solving a system of weakly coupled inequalities.
