镜像经验模态分解，可以实现信号的分析与分解，也可以做时频图(Mirroring the empirical mode decomposition, analysis and decomposition of the signal can be achieved, but also can do the time-frequency diagram)

创建一个理想的mixer输入是理想的LO信号和输入信号输出是混合后的信号。(build a ideal mixer the input is ideal LO signal and the input signal.)

使用matlab编写的各种类型的遗传算法，每一种都有注释说明 可以复制到M文件中运行(Matlab prepared using various types of genetic algorithms, each with explanatory notes can be copied to M to run in files)

此方法是层析分析法的一个较好的程序，可以用于数学建模竞赛等领域。是不错的收藏啊啊啊啊(This method is a better program, chromatography analysis can be used in areas such as Mathematical Contest in Modeling. Good collection ah ah ah ah)

最短路dijkstra问题，简单易懂的matlab程序(Most short-circuit the dijkstra problems, and to understand the matlab program)

说明：  模型中明显地体现出模型设计主要有电流调节器和转速调节器两个负反馈闭环组成， 把转速调节器的输出当成电流调节器的输入，在通过电流调节器的输出控制后面的电路。 在这里电流环为内环，电压环为外环，所以形成了转速电流双闭环控制的直流调速系统。(The model obviously shows that the design of the model mainly consists of two negative feedback loops: current regulator and speed regulator, Take the output of the speed regulator as the input of the current regulator, and control the circuit behind it through the output of the current regulator. Here, the current loop is the inner loop and the voltage loop is the outer loop, so a DC speed regulation system with speed current double closed loop control is formed.)
