Dikoussar, N. D.; Török, Cs. Automatic knot finding for piecewise cubic approximation. (Russian. English summary) Zbl 1099.65014 Mat. Model. 18, No. 3, 23-40 (2006). N. D. Dikoussar [Comput. Phys. Commun. 99, No. 2–3, 235–254 (1997; Zbl 0927.65009)] has presented a method of function parametrization based on 4-point transforms. Here, a simple stable to errors locally-optimal variant of the piecewise cubic approximation method with automatic knot finding is proposed.
