The AMLM algorithm for parameter fitting of discrete data

This MATLAB code, which pertains to the Adaptive Multi-step Levenberg-Marquardt (AMLM) algorithm, can be utilized for the nonlinear parameter fitting of discrete data. The input data is particularly required for power system current or voltage signals, which are supposed to be fitted to an exponential function.本MATLAB代码围绕自适应多步莱文贝格-马夸尔特（Adaptive Multi-step Levenberg-Marquardt, AMLM）算法开发，可应用于离散数据的非线性参数拟合任务。其输入数据特指电力系统电流或电压信号，且需将此类信号拟合为指数函数形式。
