聚类算法中的启发式算法中的FEC算法，可以处理复杂网络的问题。(Clustering algorithm heuristics in the FEC algorithm can handle complex network problems.)

本程序是对girl.bmp文件做二维的DCT，以达到压缩的目的(This procedure is done two-dimensional girl.bmp file DCT, in order to achieve the purpose of compression)

matlab编程，important，good，仅供参考(matlab programming, important, good, only for reference)

说明：  语音增强的谱减法算法实现，要有一个wav格式的声音文件(Spectral subtraction speech enhancement algorithm, there must be a wav sound file format)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

此程序是针对二元精馏塔建模，控制回流比以及进料流量来影响上层轻组分产品的浓度。分别用机理建模和最小二乘建模的方法，对精馏塔对象进行建模并比较两种模型之间的差别及分析原因。黄老师的系统辨识大作业。(This program is for two yuan distillation modeling, concentration control of reflux ratio, the feed flow rate to influence the upper light component products. Respectively by mechanism modeling method and the least square modeling, modeling of objects and the difference and reason analysis of distillation column comparison between two models. Large operating system identification of yellow teacher.)

尺度变化后的角点检测技术，基于laplace算法，效果良好(Corner detection technology, scale changes laplace algorithm, the effect is good)
