精选优质文档-倾情为你奉上Matlab求解超定方程组实例对于超定方程组，特别是非线性方程组，可以用Matlab基于最小二乘算法来进行求解，例如，求解下列方程组：一个三个未知数，九个方程的非线性方程组：cos(x3)*sin(x2)*sin(x1)-sin(x3)*cos(x1)=-0.9944 ;sin(x3)*sin(x2)*sin(x1)+cos(x3)*cos(x1)=-0.0870;cos(x2)*sin(x1)=-0.0606;cos(x3)*sin(x2)*cos(x1)+sin(x3)*sin(x1)=0.0349;sin(x3)*sin(x2)*cos(x1)-cos(x3)*sin(x1)=-0.8085;cos(x2)*cos(x1)=0.5875;os(x3)*cos(x2)=-0.1001;sin(x3)*cos(x2)=0.5821;-sin(x2)=0.8070;代码% By lyqmathfunction main()clc; clear all; close all;% cos(x3)*s
