Simu_Phase_5

this is some codes in systems

说明：  灰色预测matlab程序与散点图的绘制的matlab程序(Grey prediction matlab program and scatter diagram of MATLAB program )

matlab mean and variance 的计算 以及多次方距离计算 最后画图表现(mean and variance and plot results)

说明：  在matlab或者PSCAD中对桥差不平衡电流进行仿真计算，得到仿真结果与常规计算结果一致，此方法修改简单快捷。(In matlab or PSCAD to bridge the difference between the current imbalance in the simulation calculation, the simulation results are consistent with conventional calculations, this method is simple and quick modification.)

离散时间信号基本运算，包括序列相加相减、序列位移、序列翻转、序列周期延拓(Discrete-time signal basic operations, including the sequence of addition and subtraction, shift sequence, sequence inversion sequence cycle extension)

VC++调用matlab画图，效果很好！值得看(VC++ Call matlab drawing, the effect is very good!)

this file contains simulink model of 8 IEEE bus sytem for power transmission

this program is the simulink of logistic map

提取图像sift特征，并且showkey函数在图像上直观的显示出来(Sift extracted image features, and showkey function in the image displayed on the intuitive)

说明：  文件是学习matlab过程中关于图形图像处理的源程序(Document is the process of learning matlab image processing on the graphics of the source)
