Photonic-crystal-band-gap

这是一本很好的matlab教程，对matlab的学者有很大的帮助(this book shows the basis contents of matlab,it can help the man who study matlab.)

说明：  实现duffing方程的绘图，为工程上观察duffing混沌现象给出一个仿真的方法 (give a way to drew the picture of duffing)

与已有的代码相比，本代码不仅包含调制解调、星座图、误码率等已有功能，更添加蒙特卡洛仿真，具有更好的性能，程序会产生一些图，能看清楚调制解调的过程中一步一步的编解码过程。(Compared with the existing code, the code contains not only the modulation and demodulation, constellation diagram, such as bit error rate for existing function, more add a Monte Carlo simulation, has better performance, the program will produce some map, can see the encoding and decoding process step by step in the process of modulation and demodulation..)

matlab和lingo的使用简介，对初学者很有帮助，希望对大家有用(matlab and lingo of the use of profiles helpful for beginners, we want to be useful)

surf特征点提取以及相应的特征点匹配，matlab程序(speed up robust features (SURF), feature matching)

傅立叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。(Fourier transform can meet certain conditions expressed as a function trigonometric (sine and/or cosine functions) or their integral linear combinations.)

这是一个将时间改换到深度的程序,这是一个matlab程序(this is a program for time to depth)

涵盖了各种数字滤波器设计的例子，是日常工程设计项目制作，自学教学必备参考资料(Covering a wide range of digital filter design example is the production of day-to-day engineering design projects, self-teaching reference materials must)
