Using software optimization toolbox and adaptive approach to taper cone fitting, optimal results of taper cone fitting have been achieved. The solving algorithm of sequential quadratic programming ( SQP) and an adaptive initial point based on fitting step by step are provided for the optimal results.

利用软件的优化工具箱，采用自适应圆锥的方法进行圆锥拟合，为使优化结果达到最优，通过多步拟合得到了较优的初始点并采用序列二次规划的算法进行求解。
