平面波展开法计算二维能带结构，教FDTD快，资源占用少(Two-dimensional plane wave expansion method to calculate the energy band structures, the FDTD fast, low resource consumption)

说明：  cv模型 matlab 图像分割源码，与传统模型相比，该C V模型具有更高的分割精度。(cv model segmentation matlab source, compared to the traditional model, the CV model has higher accuracy of segmentation.)

再matlab下面实现音乐信号的端点检测。 算法是利用帧长(sign )

介绍粒子群算法的一种改进算法的实现代码，具有很大的参考意义。(Introduce particle swarm algorithm is an improved algorithm implemented code, is of great referential significance. )

经典DSP书籍，最新的第二版。chm格式，非常清晰。(classic books, the latest version of the second. Chm format, very clear.)

多线圈并行采集技术极大地缩短了扫描时间,敏感度编码(sensitivityencoding,SENSE)技术就是其中的代表(Many coil parallel sampling technology greatly shorten the scanning time, sensitivity encoding (sensitivityencoding, SENSE) technology is one of the representative, coil parallel sampling technology greatly shorten the scanning time, sensitivity encoding (sensitivityencoding, SENSE) technology is one of the representative)

Testing functions with double-byte names.

Classes which implement this interface provide methods that deal with out from a remote shell command on a device/emulator.

用matlab来解决数据拟合问题，包括四个例子程序和一个ppt(Data fitting using matlab to solve problems, including four examples of procedures and a ppt)

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)
