短时能量与过零率，别人写的，好像是可以用的，大家试试啊(Short-term energy and zero-crossing rate, someone else wrote.maybe it can be used, please try it .)

A feature selection based framework for human activity recognition using wearable multimodal sensors

这是一个通信中交织器的程序 自己用过了还可以使用 通过将图像中的集中错误分散化来实现的(this is a program about Intertexture implement)

说明：  对数字车牌的识别，详细揭示了过程，并提供了实验报告。(Digital license plate recognition, in detail reveals the process and provide an experimental report.)

说明：  出一种新 的SVPWM 算法。采用SPWM 中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM 周期中的占空比。(A new SVPWM algorithm. SPWM modulation used in the carrier wave, compared with the rules of sampling ideas, through the static coordinate system directly calculated for each reference voltage corresponding to the three-phase vector modulation wave function, which has been in a phase voltage of each PWM cycle accounting air ratio.)

说明：  有各种小波包分解的程序和子程序，能够有效快速地对振动信号进行分解。(There are various wavelet packet decomposition programs and subroutines, which can decompose vibration signals effectively and quickly.)

optimize the parameters of fuzzy controller(optimiztion of fuzzy proportional factor based on genetic algorithm)

说明：  matlab 绘图指令应用及开关语句的应用举例，有需要的同学可以看看(matlab drawing instruction applications and the application of a switch statement example, students can see the need to)

计算网络节点收缩后的节点重要度，并对电源节点和负荷节点进行归一化(node importance)
