A programmable-logic controller (PLC) is a compact computer-based electronic system that uses digital or analog input/output modules to control machines, processes, and other control modules. A PLC is able to receive (input) and transmit (output) various types of electrical and electronic signals and use them to control and monitor practically any kind of mechanical and/or electrical system.

hppc实验的数据分析，重要参数的提取，本代码适用于二阶等效电路，可以计算其中的串联电阻，并联的RC电路中的参数的值是多少，另外可以提取相应的每一个步骤所对应的开路电压，电流，以及对应的实验的时间。(hppc experimental data analysis, extraction of important parameters, the code for the second equivalent circuit can be calculated as one of the series resistance of the parallel RC circuit of the value parameter, the other can extract the corresponding corresponding to each step The open circuit voltage, current, and time of the corresponding experiments.)

一种无线传感网络的LEACH分簇算法，大家都比较需要 (Wireless sensor networks LEACH clustering algorithm )

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了

包含了多个雷达信号产生的程序，其中有线性调频信号，编码信号，等等(Contains multiple radar signals generated by the program, which chirp signal encoded signals, etc.)

一个matlab里面用的很好用的小工具 是用来算出den,num以及一切zplane的(Matlab inside with a good used small tools are used to calculate the den, num, as well as all the zplane)
