解决露天煤矿的问题，是数学建模中的考试题目。(Solve the coal mine of the problem is mathematical modeling of the exam questions.)

cdma2000的上行链路的仿真，包括编码，发送，信道，解码，rake接收等功能，完全是matlab仿真。(cdma2000 uplink simulation, including encoding, sending, letters, decoding, rake receiver functions is completely Matlab simulation.)

Code for PPG signal to estimate the HR of subjects doing intense exercises

通过计算机上的多媒体卡，按照下列过程进行声音信号的录制、处理和回放，观察处理前后的波形，同时比较声音信号处理前后的效果。 1、 将录制的信号反褶以后播放（反褶以后的信号移到t=0点开始）。 2、 将录制的信号改变取样率（相当于进行了尺度变化）以后播放。 3、 将录制以后的信号延时1s，并将幅度降低一半，接着与原来的信号相加，然后播放。(Multimedia card on your computer, follow the process for recording, processing, and playback sound signal waveform observed before and after treatment, while comparative effectiveness sound signal before and after treatment. 1, the signal recorded after deconvolution player (deconvolution signal moves after t = start 0:00). 2, the signal is changing the sample rate recording (is equivalent to a scale change) later playback. 3, after the recorded signal delay 1s, and reduce the rate by half, and then with the original signal are added, then play it.)

在secshortest中我希望只得到一条次短路,结果却出来好几条，因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。(I hope that in secshortest only a short time, the result is out of several, so when used to get at short circuit, can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest.)

此程序比较了卡尔曼滤波和粒子滤波的优缺点 (This program compares the advantages and disadvantages of Kalman filter and particle filter)

基于Simulink的小车_倒摆模糊自适应控制系统设计与仿真(Simulink based on the car _ inverted pendulum fuzzy adaptive control system design and simulation)

2D Fourier变换在光衍射方面的应用一例,对孔函数直接应用FFT2,得到衍射结果；以及FDTD方面的两个不成熟的程序(2D Fourier Transform-ray diffraction case of the application of direct application Kong FFT2 function, be diffraction; FDTD and the two immature procedures)

Fourier transform and eigen-solver are the two fundamental problems to solve. To understand better about them helps a lot in doing numerical analysis. The following are the band diagram of a 5*5 square lattice photonic crystalTM band structure for a 2D square lattice with alumina rods in air
