基于matlab的几种语音信号端点检测方法(Several based on matlab voice signal endpoint detection method)

Brownian motion. A random walk is similar to markov process, however a markov process has no memory, where a random walk uses an initial state. The next step in the walk does not necessarily depend on your current state but will be referenced from your current state, that is to say the random vector is added to your current state. depending on complexity

用传输矩阵法解一维光子晶体能带，透过率，以及群速度方向问题，概念清晰，自己编写的，应该比较容易看懂。(the transmission matrix method for one-dimensional photonic crystal, whose parameters are from the paper "negative refraction in one dimensional photonic crystal without negative refractive index material" IJMOT, 2010,5(4))

偏振图像目标识别算法，根据四个方向的偏振信息，识别目标，内含偏振图片(Polarization image target recognition algorithm, according to the four directions of polarization information, identify targets, containing polarizing picture)

用 matlab 寫的指紋辨識，有需要的下載去研究(Matlab write with fingerprint recognition, there is a need to download to study)

这是基于高斯模型的运动目标检测算法。采用空间是YUV。(This is based on the Gaussian model of moving target detection algorithm. The use of space is YUV.)

用matlab的simulink环境下搭建的光伏发电仿真模型，内含三个simulink文件，解压后直接运行(PV simulation model used to build the next matlab simulink environment, containing three simulink file, run directly after decompression)

说明：  matlab程序设计基础ppt 函数文件程序设计的基本结构(matlab program design based on function ppt document the basic structure of program design)

Keyboard-controlled interactive power spectrum demonstrator, useful for teaching and learning about the power spectra of different types of signals and the effect of signal duration and sampling rate. Single keystrokes allow you to select the type of signal (12 different signals included), the total duration of the signal, the sampling rate, and the global variables f1 and f2 which are used in different ways in the different signals. When the Enter key is pressed, the signal (y) is sent to the Windows WAVE audio device. Press K to see a list of all the keyboard commands. T. C. O Haver

这是三组程序，分别计算hibert变换，小波时频分布，wigner-vill分布，并且画出谱图(This is three groups of program, calculate hibert transform, wavelet time-frequency distribution, wigner- vill distribution, and draw the spectrogram)
