Least Significant Bit Steganografi

全国电子设计大赛相关的需要注意的培训内容！这是２００７年我们老师给我们讲的一些东西！-National Electronic Design Contest-related training need to pay attention! This is a teacher in 2007 told us something!

VB进行大整数乘法运算实例，实现两个超大整数的相乘功能，是数学计算器中的一个功能部分，请注意乘数和被乘数都必须由数字组成。可以显示计算过程，可随机生成两个大整数以便测试，计算结果将显示在下边的文本框中。

利用RSS进行室内定位仿真实验在RSS指纹数据库中抽取离线数据集；利用抽取出来的数据集作为KNN算法的训练数据集；(RSS is used for indoor positioning simulation experiments to extract offline data sets from RSS fingerprint database, and the extracted data sets are used as training data sets of KNN algorithm.)

说明：  通过一个C++例子，来学习C++的重载。这里面包括几个重载的例子(Through a C + + example, to learn C + + overload. There are several examples of overloading)

说明：  这是将波动方程分解为上行波下行波的源程序 把两个源代码放在一起，运行即可了！(This is the wave equation will be decomposed into up-going wave downlink wave source source code of the two together, you can run the!)

移动端使用,具有很多的功能,方便调用,推荐给使用(Mobile terminal, with many functions, easy to call, recommended for use)

看过很多无人机建模的文章，这篇是精华，建议有需要的多研究本文(Read a lot of the unmanned aerial vehicle modeling article, this is the essence, suggest the need more research article)

说明：  此代码为matlab寻优测试代码，并且画出进化图，只要把目标函数带入测试即可。(This code is matlab optimization test code, and draw the evolution diagram, as long as the objective function into the test.)

pb开发的库存管理系统-pb development of the inventory management system

将matlab中绘制的图像转为IGES格式导出便于在UG/PROE中打开(The export of the images drawn in MATLAB to the IGES format is easy to open in UG/PROE)
