MATLAB-S-Function

用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。 （1） 观测数据应该有一定的多普勒频偏D f（-10kHz〈D f〈+10kHz）； （2） 加入高斯白噪声，使其信噪比为-20dB； （3） 捕获成功后，应给出捕获标志，并给出估计的频偏和码偏值。(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)

这是本人自己遍的matlab程序，即对做过fft变换的相位嵌入水印的程序(this is my own times of Matlab procedures, that is done on the phase transformation fft watermark embedding procedures)

混沌工具箱ver.2.0,程序没问题，可以用。有c-c法求时延和嵌入维数的，求最大李雅普诺夫指数的等。(Chaos Toolbox ver.2.0, the program is no problem, you can use. There cc method for delay and embedding dimension, for the largest Lyapunov exponent and so on.)

为圆柱体定义一种有效地多边形网格表示，并调整对表示的选择 (《计算机图形学（第三版）》P139/3.25)(For the cylinder to define a polygon mesh that effectively, and that the choice of adjustment (" Computer Graphics (Third Edition)" P139/3.25))

说明：  这是个混沌理论中分岔图的源代码，通过这个代码，我们可以看出它走向混沌的过程，进而分析它的动力学特性，希望对大家有用(This is chaos theory in the bifurcation diagram of the source code, through this code, we can see the process it into chaos, and then analyzes its dynamics, we hope to be useful)

这是一个很好的学习SIMULINK建模的基础教程，通过该课程的学习可以快速掌握SIMULINK的基本技巧。(This is a good basis for learning SIMULINK modeling tutorial, by the course of the study can quickly grasp the basic skills SIMULINK.)

Frankle Retinex算法 效果很不错(matlab code for Frankle Retinex，which gives good results)
