(四)Least-squares Solution(最小二乘解) 1、Suppose there exists N data points:(假设存在N个数据点:) 只有β0和β1是未知,其他均为已知 (五)Polynomial Curve Fitting:polyfit()(多项式曲线拟合) 1、Curve fitting for polynomials of different orders(不同阶多项式的曲线拟合) 示例代码: x = [-1.2 -0....
The least-squares solution to A*X = B is X = R\C. 输入方程 Ax=B 的矩阵和右端项,不返回正交基 Q ,而是 Q′∗B=Q−1B。 猜测这种方式相比于计算矩阵 Q 的计算代价要来的小。 因此x=R∖(Q∖B)=R∖C 是完整的求解过程。
Weighted Least Squares Create a matrixAand vectorbfor the problemA*x = b. Create a vector of relative observational weights, and compute the weighted least-squares solution. a1 = [0.2; 0.5; 0.6; 0.8; 1.0; 1.1]; a2 = [0.1; 0.3; 0.4; 0.9; 1.1; 1.4]; A = [ones(size(a1)) a1 ...
For linear least squares without constraints, the problem is to come up with a least-squares solution to the problem Cx = d. You can solve this problem with mldivide or lsqminnorm. When the problem has linear or bound constraints, use lsqlin. For general nonlinear constraints, uses lsqnonlin...
