觉得很好的一个Matlab程序想和大家一起分享，互相学习。(A Matlab program feel good and you want to share, learn from each other.)

In power engineering, the power flow study (also known as load-flow study) is an important tool involving numerical analysis applied to a power system.

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

切比雪夫插值（利用切比雪夫点进行多项式插值），对连续函数进行逼近。(Chebyshev interpolation (using Chebyshev polynomial interpolation points), for continuous function approximation)

Application of LSB Based Steganographic

电力电子、电机控制系统仿真模型 经典仿真源程序 洪乃刚版本(Power electronics, motor control system simulation model version of the classic simulation source Hong Naigang)

基于MATLAB的PCA和KPCA的实现，有图，有返回的参数，绝对可以运行！(Based on the PCA and KPCA MATLAB to achieve, there are plans to return to the parameters, the absolute can run!)

通信过程的MATLAB建模，过程清晰，分析到位，感觉不错(MATLAB modeling the communication process, process definition, analysis in place, feeling good)

使用有限差分法和分裂步傅里叶解法求解抛物方程，并增加散射体和地形的建模仿真。(Using the finite difference method and the split-step Fourier solution for solving the parabolic equation, and increase the scatterer and terrain modeling and simulation.)
