说明：  LM莱文博格马夸特优化算法，python语言(this is a file of LM algorithm which was wroten by python language)

说明：  此程序为分段最小二乘算法曲线拟合,可对一模型进行分段拟合,增加准确性和精确度.(This program is sub-least-squares curve fitting algorithm can be fitted to a sub-model to increase the accuracy and precision.)

以上是两个内点法程序，原仿射内点法，对偶仿射内点法。初始内点需要自己给出，自动求解初始内点的程序下次发送(These are the two interior point method procedure, the original affine interior point method, dual affine interior point method. Initial interior point needs its own given the initial interior point solution of automatic procedures to send the next)

可以方便求解非线性偏振旋转锁模光纤激光器的脉冲传输(You can easily solve the nonlinear polarization rotation mode-locked fiber laser pulse transmission)
