PID控制MATLAB仿真第二版，介绍关于PID的各种控制。(MATLAB simulation of the second version of PID control is introduced on a variety of PID control.)

说明：  利用BP神经网络作为分类器，对公司财务进行分类，构造分类器，结果表明能够很好的将数据分类，有兴趣可以看看。(BP neural network is used as a classifier to classify corporate finance and construct a classifier. The results show that the data can be well classified and you can have a look if you are interested.)

三相滞环控制有源电力滤波器。采用三相PWM整流器拓扑，基于瞬时功率理论的滞环控制(Closed-loop control of three-phase active power filter, three-phase PWM rectifier weapon as topology, instantaneous power theory based hysteresis control.)

在matlab运行环境下 实现霍夫曼编码及霍夫曼译码(Huffman coding matlab implementation)

ofdm-dvb-t系统的仿真，有ofdm 实现模块，误码率计算，等模块。(ofdm- dvb-t system simulation, ofdm achieve module, BER, and other modules.)

说明：  随机森林是一种有监督学习算法，是以决策树为基学习器的集成学习算法。随机森林非常简单，易于实现，计算开销也很小，但是它在分类和回归上表现出非常惊人的性能，因此，随机森林被誉为“代表集成学习技术水平的方法”。(Random forest is a supervised learning algorithm, which is an integrated learning algorithm based on decision tree. Random forest is very simple, easy to implement, and the cost of calculation is very small, but it shows amazing performance in classification and regression. Therefore, random forest is known as "the method representing the level of integrated learning technology".)

区域生长算法，一个老美写的，算法写的相当巧妙，需要花点时间好好看下。(Region growing algorithm, written by an old America, the algorithm is quite clever to write, take time to properly see next.)

This code consist of QAM CDMA BPSK and other modulation codes
