牛顿迭代法(Newton's method)又称为牛顿-拉夫逊(拉弗森)方法(Newton-Raphson method),它是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。多数方程不存在求根公式,因此求精确根非常困难,甚至不可能,从而寻找方程的近似根就显得特别重要。方法使用函数f(x)的泰勒级数的前面几项来寻找方程f(x) = 0的根。牛顿迭代法是求方程根的重要方法之一,其最大优点是在方程f(x) = 0的单根附近具有平方收敛,而且该法还可以用来求方程的重根、复根,此时线性收敛

一般的线性方程我们可以用最小二乘来解,一般的非线性方程我们可以用LM来解。
这里是线性微分方程组,所以我们采用最小二乘来解。
关键是构造出最小二乘形式,微分可以通过前后数据差分的方法来求。
不过这里还有一个技巧就是如果数据前后帧间隔过大,可以先插值,再对插值后的数据差分如果实际测量数据抖动过大导致插值后差分明显不能反映实际情况,可以先对数据平滑(拟合或是平均)再求差分。(We can use least squares to solve general linear equat
