K近邻方法实现0到9数字的模式识别问题。可扩展性很强，方面实现训练和识别。(K nearest neighbor method to achieve 0 to 9 digit pattern recognition problem. Highly scalable, achieving training and recognition.)

说明：  MATLAB是由美国mathworks公司发布的主要面对科学计算、可视化以及交互式程序设计的高科技计算环境。它将数值分析、矩阵计算、科学数据可视化以及非线性动态系统的建模和仿真等诸多强大功能集成在一个易于使用的视窗环境中，为科学研究、工程设计以及必须进行有效数值计算的众多科学领域提供了一种全面的解决方案，并在很大程度上摆脱了传统非交互式程序设计语言（如C、Fortran）的编辑模式，代表了当今国际科学计算软件的先进水平。　(MATLAB is a U.S. company' s main face mathworks scientific computing, visualization and high-tech interactive computing environment programming. It numerical analysis, matrix computation, scientific data visualization and nonlinear dynamic systems modeling and simulation, and many other powerful features in an easy to use integrated Windows environment for scientific research, engineering design and the need for effective numerical calculation many fields of science provides a comprehensive solution, and largely out of the traditional non-interactive programming language (such as C, Fortran) of the edit mode, on behalf of the current international advanced level of scientific computing software.)

用lanczos求特征值的matlab程序(with lanczos eigenvalues for the Matlab procedures)

说明：  实现脊线提取，处理信号工具，基于小波变换，可以进行脊线提取(Ridges extraction and signal processing are implemented. Ridge extraction can be done based on wavelet transform.)

此程序是关于经济学中布莱克斯科尔斯模型 的matlab实现(This procedure creates a three-dimensional plot showing how gamma changes relative to price for a Black-Scholes option. Recall that gamma is the second derivative of the option price relative to the underlying security price. The plot shows a three-dimensional surface whose z-value is the gamma of an option as price (x-axis) and time (y-axis) vary. It adds yet a fourth dimension by showing option delta (the first derivative of option price to security price) as the color of the surface)

计算声音的旋律，利用了听觉模型和相关函数。(Calculation of the melody of the voice)

模式识别工具箱的内容非常好用，找了好久才找到的(The contents of the toolbox is very useful for pattern recognition. Lots of downloads)

Library for Robotics Code, using aforge Library

This toolbox provides tools to create sophisticated MATLAB graphical user interfaces that resize gracefully. The classes supplied can be used in combination to produce virtually any user interface layout.
