自己写的两种susan边缘检测算子。能够较好的实现弱边缘的精确检测。(Susan wrote their own edge detection operator. Better able to accurately detect the weak edge.)

说明：  光子晶体带隙计算的例子，以前在3.5版本模型库里面有，但是4.2里面么了，希望对大家有所帮助。(Photonic band gap calculation example, the previous 3.5 version of the model library in there, but what a 4.2 inside, we want to help.)

gabor变换是非平稳信号处理的有效方法之一，在时频平面内可获得最佳划分(gabor transform one of the effective methods of non-stationary signal processing, get the best in the division of the frequency plane)

matlab在自动控制原理的的应用，ppt讲解格式，详细，并且配有例题的源代码，面向实际，很适合解决自动控制原理方面的问题(Matlab in control of the application of the principle, ppt format to explain in detail, Examples and equipped with the source code, to face reality, the solution is very suitable for the automatic control theory problems)

that is matlab code for linear regression , please enjoy!

matlab自学的六十多个简单易学的小程序，学习完这六十多个程序之后，你的matlab水平将得到很大的提高！(matlab for learning by yourself!matlab for learning by yourself!matlab for learning by yourself!matlab for learning by yourself!)

擅 蔓：以人脸的表情识别为实验背景， 分析了在对人脸表情的识别过程中，单个独立分薰对识别率的影响，由此进一步总结了在表情识 别中如何更有效地选取独立子空间，以实现在不影响识别率的前提下，减少用于构成独立子空问所需的独立分量的个数。 独立成分分析；表情识别；独立子空间 (Good man: Face to face identification for the experimental background, the analysis of facial expressions in the identification process, a single smoked separate the impact of the recognition rate, thus further summarized in the expression recognition of how to more effectively select the independent sub-space in order to achieve the recognition rate does not affect the premise, for constituting a separate sub-reducing space required for the number of independent component. Independent component analysis expression recognition independent subspace)

说明：  采用墨西哥帽子小波函数，构造一维连续小波变换的程序(The use of Mexican hat wavelet function, construction of one-dimensional continuous wavelet transform procedure)

说明：  相信对初学者比较有用，欢迎大家下载并交流与指导。(Believe that the more useful for beginners, are welcome to download and exchange and guidance.)

本文介绍了基于MATLAB软件在《信号与系统》课程教学中的仿真实验,通过抽样信号的表征、周期方波信号的傅立叶级数分解与合成、余弦信号的相加与相乘、RLC带通滤波器的频率特性等仿真实验,说明了将MATLAB应用于教学实践中的重要作用和意义。(This article describes the MATLAB-based software in the " Signals and Systems" course teaching simulation, by sampling the signal characterization, cycle square wave signal of the Fourier series decomposition and synthesis, and the sum of cosine signal is multiplied, RLC bandpass filter the frequency characteristics simulation, MATLAB used to illustrate the important role of teaching practice and significance.)
