在这个世界请帮助人们

说明：  用matlab实现的fp树。目的是发现频繁项集，但是本代码只是实现了fp树(Fp tree with a matlab implementation. Aim is to discover frequent itemsets, but only realized the fp tree code)

matlab串口通信，实例教程，基于GUI的matlab串口通信编程(matlab serial communication, tutorial examples, GUI-based serial communication programming matlab)

其中包括3个c++搜索源程序和2个matlab编写的fdtd程序(including three c search source and two Matlab procedures prepared by the fdtd)

实现了JPEG标准的图像编译码流程。读取一个灰度图像，采用DCT变换、量化、Zigzag扫描和游程编码等步骤实现编码，译码端采用对应的逆操作进行译码。程序中可设置不同的量化系统，实现不同的压缩比和压缩效果。

MATLAB基于点的图像配准程序，请大家分享。(MATLAB-based point image registration procedures, please share with you all.)

基于MATLAB和usb外置声卡的信号回检，检测信号频率，幅值，功率等。(Based on MATLAB and usb external sound card signal back to check, test signal frequency, amplitude, power, etc..)

vmware虚拟机开机自动运行，并隐藏后台运行(vmware virtual machine to start automatically and run in the background hidden)

该程序为标准粒子群算法源程序，可以在此基础上改变参数，对程序进行优化(The program is the standard particle swarm algorithm source code, you can change the parameters on this basis, the program optimization)

matlab时频分析工具箱，短时傅立叶变换STFT，gabor变换，小波变换，维纳滤波。

可以对音频进行水印嵌入与提取，完整的源代码可以直接在matlab上运行(Can be carried out on the audio watermark embedding and extraction, complete source code can be run directly in matlab)
