基于fft的匹配追踪算法，且ff与tMATLAB中自带的源程序不尽相同(Fft-based matching pursuit algorithm, and ff the source code comes with tMATLAB in different)

基于时延估计的目标定位与跟踪：编写了一个Matlab GUI，可以实现三围空间目标的定位，以及运动目标的跟踪(The Target_Positioning_&_Tracking Through Time-Delay-Estimation.)

这段代码主要是实现二阶巴特沃斯高通滤波器，本段代码全部用MATLAB语言实现的。(This code is to achieve second-order Butterworth high-pass filter, the above code to achieve the full use of the MATLAB language.)

介绍MATLAB的ppt课件，有助于在短时间里学会运用MATLAB。对数学建模很有帮助。(Introduction MATLAB-ppt courseware, helping in a short time learn to use MATLAB. Useful for mathematical modeling.)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

这是在matlab的基础上开发出的pid控制器源代码(It is developed on the basis of matlab pid controller source code)

利用平面波展开法来计算完整光子晶体能带图的两个程序，比较好用(Using the plane wave expansion method to calculate the complete photonic bandgap diagram of the two programs, seem to work better)
