The Method of Least Square with the Second Order of Hermite Interpolation Condition

The methods of least square with the first order of Hermite interpolation condition were studied by Yan Ning-sheng. On this basis, this paper studies the methods of least square with the second order of Hermite interpolation condition, and gives the concrete expressions of fitted curve using the methods of least square with the second order of Hermite interpolation condition. Finally, the authors design the procedure for solving this Hermite interpolation fitting curve parameters using Lingo modeling language.
