说明: 在科学与工程计算中,经常遇到求解非线性方程组的问题;非线性方程组在收敛速度及收敛性比线性方程组要差,特别对于非凸的非线性方程组,其求解更是困难。下面简要介绍非线性方程组的三种解法——牛顿法、拟牛顿法、同伦算法,分析三种解法的适用性,并附Matlab原程序。(Scientific and engineering computing, often encounter the problem of solving nonlinear equations speed of convergence of nonlinear equations and linear equations worse than convergence, especially for non-convex nonlinear equations, which is even more difficult to solve . The following briefly describes three solutions to nonlinear equations- Newton method, quasi-Newton method, homotopy method, the applicability of the three solutions, along with Matlab original program.)

递推最小二乘
说明: 一般的最小二乘通常是一次拿到全部的数据, 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘,每次使用最新的测量值,来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)
