使用fdtd算法计算光子晶体的模式折射率

应用背景该程序是第九届飞思卡尔摄像头组的参赛程序，是用的芯片是KL26,底层库是野火的底层库。本程序下载到芯片里，可以稳定完整的跑完一圈，过坡道无压力，在实验室跑的非常稳定，新手拿过去，可以很快让小车跑起来。关键技术还有手机软件蓝牙调参数的程序，调参软件的程序也很简洁，非常好理解。包括移植到底层的函数也做了详细的注释，方便调小车的参数，提高了调车的效率。而且KL26和K60差不多，可以很方便地移植到K60的上面，程序可读性也很强，加了较多注释，很好理解。使用的是卡尔曼滤波。

一款价值无量的曲线控件,只要在数据库导就可生成漂亮的拟合曲线-A curve of the control is of immeasurable value, as long as guide in the database can be generated fitting curves of a beautiful

webrtc中提取的AEC库，从webrtc开源项目中提取，可以使用，可以作为学习之用，现在关于开源aec算法的 代码少，这个确实还不错

应用背景简单地数据处理，计算两组数据间的相似性，应用在推荐系统的数据处理中，其他方向的数据处理也适用，比较简单易学，供学习交流。关键技术用C++语言实现的简单数据处理，在很多研究方向可以用于预处理数据，计算数据的相似性也是很多研究方向需要用到的，希望对大家有用。
