说明：  此文件为MATLAB中常用的函数逼近的算法集。所有算法由本人亲自调试通过，且算法风格简介明了，代码格式美观。(This document is commonly used for the MATLAB function approximation algorithm for the set. I personally by all the algorithms, through debugging and algorithm profile style and clear, attractive format code.)

说明：  数学实验matlab的好程序，给matlab的初学者(Good mathematical experiment matlab program to matlab for beginners)

这是一个KNN分类器的matlab函数（K近邻分类器）,可自由选择参数k(it s a KNN classifier program of the matlab ,you can chose the parameter k to conduct the classify procedure )

关于matlab数据预处理的课件ppt，以及一些个人的整理，比如matlab某些函数的应用。(About the matlab data preprocessing courseware ppt, as well as some personal finishing, such as some matlab function.)

运用FFT技术来综合和分析电话拨号的过程，matlab来分解了这一过程，希望能提供帮助( TOUCHTONE Use FFT to synthesize and analyze telephone dialing The dual tone multi-frequency (DTMF) standard specifies that the tone generated by a button on a telephone key pad is the sum of two sinusoids, with frequencies determined by the button s row and column. The dial pad on the upper left allows you to select buttons and generate the corresponding tones. The signal plotted on the upper right is a recording of the FAX number for the MathWorks being dialed. You can replay the entire signal, or select individual segments. The power plot is the magnitude of the FFT of the signal being played. What is the MathWorks FAX number?)

说明：  瑞利衰落信道模型，可以运用与ofdm信道估计和时域均衡(Rayleigh-channel-implementation-master)

K-means algorithm for gray-scale images. Implemented on MATLAB for segmentation.

噪声下的信号检测，及Matlab 仿真验证(Noise under the signal detection, and the Matlab simulation)

根据m序列的原理，用于产生任意位的小m序列。(According to the principle of m sequences, used to generate random bit sequence of the small m.)

这是一个图像分割程序，基于snake方法，对初始位置选择要求较高，在matlab环境下调试运行(This is an image segmentation procedures based on the snake, location of the initial demand for a higher choice, In Matlab environment debugging operation)
