simple function to test watermarking

说明：  這是一個求數獨遊戲的m-file 在matlab的命令窗口 鍵入>> sudo7 或者run sudo7 的m-file 之後在 9x9 的方格內 填入 數獨的問題 按下 "計算是否有解" 的功能鍵 若不是存在多組的解，則可以 按下 "顯示結果" 的功能鍵， 也可以載入作者測試的"date1"或"date2" 但不可載入及修改"condition"(This is a Sudoku game for the m-file in matlab command window type>> sudo7 or run sudo7 the m-file after the box in the 9x9 Sudoku Fill in the question of pressing the calculate whether the solvability feature key if it were not for the existence of multiple solutions, you can press the show results of the function keys can also be included in the authors test date1 or date2 but not loading and modification of condition )

使用逐幸存算法，对有码间串扰的信道参数和进行估计发送信息进行估计(Algorithm used by survivors, for there is intersymbol interference channel to send information to estimate parameters and to estimate the)

汽车七自由度的振动程序，可以求解固有频率，悬架的动挠度等，欢迎大家下载学习与交流(vibration of the car with seven degrees)

基于PCA的人脸识别matlab代码。建立特征脸空间，而后将预存人脸图像和待识别图像投影到特征脸空间上，可以得到较高的识别率(Based on PCA face recognition matlab code. The eigenface space is established, and then the stored face image and the image to be recognized are projected onto the feature face space, and a higher recognition rate)

多址接入协议仿真。ALOHA协议由于数据包之间的碰撞而导致性能下降，CSMA协议能够提供较高的容量，但它应用于无线通信系统时，容易受到“隐终端”问题的影响。而ISMA协议通过中央基站控制移动终端的数据包传输，降低了数据包之间发生碰撞的概率以及隐终端问题。 

MATLAB 有约束信赖域算法，以四元多项式为算例 适用于学习最优化算法的数学专业学生以及其他数值分析课程的同学， 程序清晰，对MATLAB的学习也有很大的帮助，同时程序还有一些不足，读者自己须根据实际问题更正。(MATLAB constrained trust region algorithm to quaternion polynomial example for the application of optimization algorithms in the learning of mathematics students, as well as other courses in numerical analysis of the students, the program clearly and learning to MATLAB is also a great help, but the procedure also There are a number of shortcomings, the reader himself to be corrected in accordance with the actual problem.)
