下图为根据上面得到的A、B系数,利用matlab拟合的人口模型曲线 例子2:我想要拟合如下模型, 由于缺乏观测量,就自导自演,假设4个参数已知A=5,B=1,C=10,D=2,构造100个随机数作为x的观测值,计算相应的函数观测值。然后,利用这些观测值,反推4个参数。 // A simple demo of Gauss-Newton algorithm on a user ...
上篇博文:Newton – Raphson Iteration Procedure of TOA - Based Positioning仿真了NLS中的牛顿—拉夫森仿真的TOA定位。 这篇博文采用同样的体系仿真高斯—牛顿的TOA定位。 这些内容的根基在:NLS ALGORITHMS of TOA - Based Positioning 仿真条件和上篇博文一致。 首先给出一次实验定位示意图,信噪比为30dB。 肉眼可以...

Open in MATLAB Online Hi so I've ran in to a problem I was wondering if someone could help me resolve. This is my script: tvec = [0 0.2 0.4 0.6 0.8]'; Pvec = [5.1 5.9 6.4 7.5 8.3]'; F =@(x) x(1)*(exp(x(2).*tvec)) - Pvec; ...
所有实验都是用个人电脑计算机上的MATLAB(R2017b)实现。所有的计算都是从初始向量x(0)=zeros(n,1)开始的,一旦解的相对误差(relative error,RE)小于10-6,迭代终止,其中相对误差定义为: 对于随机生成的矩阵,将gG-S和gmG-S方法的迭代步数(IT)和计算时间...
