此程序是matlab中有关平滑去噪中常用的小波的程序，简单使用，其中的注释详细，对每个变量的注释都很清楚(Matlab in this procedure are commonly used on the smooth wavelet denoising procedure, simple to use, with detailed explanatory notes for each variable are well aware of the Notes)

createimage函数实现当前零水平集（演化曲线）在原图上的显示和嵌入函数u的重新初始(Createimage functions implementing the current zero level set (curve evolution in the display on the original) and inline function u initial again )

简易模拟时钟，使用MATLAB的GUI开发而成，可以获取桌面时钟数然后在模拟钟面上显示，每隔一秒刷新显示！(Simple analog clock, a GUI was developed using MATLAB, you can get a desktop clocks and analog clock face on display, refresh the display every second!)

the code i have uploaded estimate the position of speaker,in environment put a number of microphones that by extended kalman filter estimate the position of speaker

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。(Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR, the human ear can identify audio.)

谱估计中的Esprit算法，利用matlab进行仿真找出信号的频率，精度较高(Spectral estimation algorithm in the Esprit, the simulation using matlab to find the signal frequency, high precision)

Good practical guide to Matlab

用matlab处理矩阵和向量的各种函数，解决各种难题，并让程序具有通用性，鲁棒性等，英文(Matlab matrix and vector processing with a variety of functions, solving problems, and let the program has the versatility, robustness, English)

create new based on mean and variance of the each cluster

说明：  光谱数据预处理之小波去噪，包含两个数据文件(Wavelet denoising for spectral data preprocessing)
