广义最小二乘的算法结构，广义最小二乘递推的每一步用两步递推算法，先把噪声参数和模型参数均给个初值，然后第一步先假设噪声参数已知，用最小二乘估计出模型参数，第二步再用最新的模型参数来估计噪声参数，如此循环直到辨识精度达到指定要求或者可用数据用完为止(Generalized least squares algorithm structure, generalized recursive least squares every step of the two-step recursive algorithm, first noise parameters and model parameters to the initial value, then the first step is to assume that the noise parameters are known, with the smallestsquares to estimate the model parameters, and the second step, and then the latest model parameters to estimate the noise parameters, and so on until the identification accuracy specified requirements or available data is used up)

说明：  实现了对函数的奇偶分频的频谱分析，DFT什么的，包括了4个基础的信号处理实验代码(To achieve parity of function analysis of frequency spectrum)

使用鏡子鏡射的原理，也就是將接收點鏡射之後，求取傳送點與接收點的距 離，而因為公式(1)及公式(8)，可知角度與距離有關係，可以使用這個公式來直 接代入公式(10)之中。(. The receiver is located at the center of a 50-m*50-m room and transmitter is moved along a straight from 2m to 20m from the receiver. Show the received power in decibels versus distance for the LOS path, and include all the first-, second-,third-order reflections. (Gt = Gr = 1.6, f = 1GHz, a =-0.7, Pt = 1W))

说明：  对多机电力系统进行小干扰稳定分析 可以计算特征值，特征向量(Of multi-machine power system small signal stability analysis can calculate the eigenvalue, eigenvector)

几种验证代理模型精度时常用的多项式函数。程序可在matlab中绘制相应函数图形，计算对应点处函数值，后续在代理模型中可以验证代理模型精度。(Several verification surrogated models accuracy is commonly used when polynomial functions are used. The program can draw the corresponding function graph in MATLAB, calculate the function value at the corresponding point, and then verify the accuracy of the agent model in the proxy model.)

信号FFT的MATLAB的编程，对于初次使用MATLAB的人具有很好的参考价值(the code of FFT)

用于交流异步电机转子断条仿真。给出频谱特征分析结果。(AC induction motor for the simulation of broken rotor bars. Gives the spectral characteristics of the results.)
