Matlab code to detect Harris corner points in user selected area.

该文件是学习matlab的经典教材，国内无法找到，本人从国外所得。(this book is the classical textbook for matlab.it is easy to learn and grasp by matlab engineers.)

matlab源码关于模糊K均值聚类算法，很好的，适合大家下载研究学习(matlab source code on the fuzzy K-means clustering algorithm, very good for everyone to download research study)

说明：  用四阶经典龙格库塔算法求解5阶细胞神经网络状态方程，得到5路超混沌序列。(With the fourth order classical Runge-Kutta algorithm for 5-order cellular neural network state equation, 5-way super-chaotic sequence are generated.)

提出了一种新的基于小波包变换 和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题； 并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了 小目标的精确检测(The wavelet packets were applied to decompose the image into pyramid subbands at different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact detection result was obtained. )

In mathematics, the method of characteristics is a technique for solving partial differential equations. Typically, it applies to first-order equations, although more generally the method of characteristics is valid for any hyperbolic partial differential equation. The method is to reduce a partial differential equation to a family of ordinary differential equations along which the solution can be integrated from some initial data given on a suitable hypersurface. This software is an example of implementation of characteristics method in a definition of convergent-divergent nozzle.

计算小波熵程序，先计算出小波分解后的小波系数，对其求熵得出结果。(Wavelet entropy calculation program, first calculate the wavelet coefficients of the wavelet decomposition, the results of its request entropy.)

Aim: do walsh coding with hamming distance.To compare WALSH decoding for synchronous CDMA with decoding using hamming distance. a) System should be supplied with correct/ corrupted version (one/ two bit) of transmitted walsh code(s) b) System should also have table for correct codes(walsh codes) c) System should ab able to deocde the same using hamming distance property. d) Copmare resutls for corrupted code(s) to check the efficacy of WALSH decoding technique (as in above experiment) compared to hamming distance decoding.
