通过最小二乘辨识系统模型，并进行必要的分析，是上系统辨识课的实验内容，有程序和报告(By least squares identification system model and the necessary analysis on System Identification lesson experimental content, procedures and reporting)

33节点配电网前退回代法潮流计算程序。可以计算功率损耗，是至今为止比较完善的程序(33-node distribution network return on behalf of the flow calculation procedures. Can calculate the power loss, so far a relatively complete program)

最速下降法就是梯度下降法,可以用于求解最小二乘问题(线性和非线性都可以)。可以说是求解机器算法的最古老、最经典的模型，另一种常用的方法是最小二乘法。(The steepest descent method is the gradient descent method, which can be used to solve the least squares problem (both linear and non-linear). It can be said that it is the oldest and most classical model for solving machine algorithm. Another commonly used method is the least square method.)
