基于小波变换的数字水印算法matlab代码，含有各种攻击的效果对比，对做毕设的同学应该有帮助。(Digital Watermarking Based on Wavelet Transform algorithm matlab code, containing a variety of attacks on the effect of contrast on the Bi-based students should do help.)

Matlab toolbox wave 3example小波计算,希望对大家有用(Matlab toolbox wave 3example Wavelet basis, everyone would like to be useful)

这是薛定宇的经典书籍：高等数学问题的MATLAB求解~非常有用，非常详细，欢迎大家下载~(This is of Xue Dingyu the classic books: MATLAB higher mathematics problem solving to be very useful, very detailed, welcome to download to)

simulink仿真实现DCDC升降压变换。内涵编号的文件以及参考文献进行参数设置(simulink Simulation DCDC step-down conversion. Connotation numbered files and references set parameters)

该文件是学习matlab的国外经典教材，在国内也没有电子书，本人从国外所得(This book is written for the matlab primers of engineering by University of Cabriage.It s easy to learn and grasp.)

关于混沌系统同步的滑模变结构仿真，采用s函数，很有意义。(Synchronization of chaotic systems on sliding mode simulation, using the s function, it makes sense.)

求峰值点的子程序，可用于信号的频率等参数估计(And the peak point of the subroutine, may be used to signal the frequency parameter estimation)

说明：  通过simulink建立电磁阀模型，通过pwm控制，控制电磁阀的开闭(The model of solenoid valve is established by Simulink, and the opening and closing of solenoid valve are controlled by PWM control)

最优分割的基本思路是给定一个数据序列和分层数，通过搜索所有可能的划分方案，找到段内离差平方和的总和最小的一种方案作为最终划分方案。这里给出最优分割法的Matlab源程序(The basic idea is optimal partition for a given data sequence and hierarchical number divided by searching all possible solutions to find the segment and the sum of the squared deviations smallest division of a scheme as a final solution. This gives the optimal segmentation Matlab source)
