运用加权最小二乘法进行电力系统状态估计 具有较好的收敛性 但适合于较小的系统-Using weighted least squares state estimation of power system has a good convergence, but for smaller systems

非线性最小二乘法参数估计程序，利用该程序可以对已知解析解的物理过程进行参数估计，估计出线性无关的参数-Parameter estimation of nonlinear least squares method

两个仿真分别实现LS（最小二乘法）和MMSE（最小均方误差）信道估计。-Two simulations were realized LS (least squares) and MMSE (minimum mean square error) channel estimation.
