说明：  求最小值的方程原文件及运行命令文件，可以方便快捷的求出非线性有约束的最小值(Seeking the minimum value of the equation of the original documents and run the command file, you can find convenient and efficient non-linear constrained minimum)

This is the thwaites method for boundary layer over flat plate . This is an empirical method based on the observation that most laminar boundary layers obey the following relationship .it will help our calculate coefficient drag , velocity over flat plate.

求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。(The short-time zero-crossing rate, short-time energy and short-time autocorrelation characteristics of speech signal are solved, and the experimental results are analyzed. The pitch period and resonance peak of speech signal can be analyzed by the parameters obtained by time-domain analysis method.)

利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)
