This is Uncstned particle filter demo code.

二维光子晶体能带结构算法和三维光子晶体能带结构算法，主要是平面波展开法计算的(Two-dimensional and three-dimensional photonic crystal band structure algorithms)

主成分分析，用于海洋、气象，将多个变量通过线性变换以选出较少个数重要变量的一种多元统计分析方法。(Principal component analysis for the ocean, weather, several variables by linear transformation to elect a number of multivariate statistical analysis less important variables.)

这是一个详细的matlab中som的使用方法，每一步有详细的注解并伴有图片显示，使大家快速的入门并掌握住(This is a detailed matlab in som way to use each step with detailed comments and accompanied by pictures show, so that we can quickly get up and grasp)

程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。(Program uses a two-layer loop on calculate displacement spectra. Cycle based on seismic waves obtained the previous step under the displacement, velocity and acceleration are next after the interval velocity and Acceleration outer loop implementation in different natural period of structure (frequency) the response under earthquake wave.)

本代码利用同态滤波算法来对图像进行处理，从而实现增强图像质量，使用的是matlab环境(this code is used to accomplish the image enhancement , using homomorphic filtering aglorithm)

说明：  里面有MATLAB的SVM工具箱和基于wine的数据分类程序源代码，可实现数据的分类(SVM Toolbox of MATLAB)
