使用matlab就行计算和求值偏微分方程组，提供一些程序语言参考(using matab to analyze the partial differntial problem)

OFDMA仿真代码,可以直接运行，包含很多M文件，可以分块使用，非常有用。(OFDMA simulation code can run, including a lot of M file, you can block use, very useful.)

通过matlab调用xfoil程序，对翼型升阻力力矩进行计算，并将计算结果生成结果文件，程序中对三种翼型进行了计算，用户可根据需要删减或复制程序的相同部分即可(Xfoil by calling the same part of matlab procedures, the airfoil lift and drag torque is calculated, and the calculated results file is generated, the program for the three airfoils were calculated, the user can cut or copy the program as needed to)

用七元线形天线阵（ULA） 已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个 源信号,假设它们的频率：0.015, 0.05, 0.02, 0.035 四个源信号的方向分别为：pi/4 pi/3 pi/6 3pi/4 求： 1）在不加入噪声的情况下,画出传统波束形成法、Bartlett波束 形成法、Capon波束形成法的空间谱图； 2）在加入高斯白噪声的情况下,假设信噪比为10dB，画出传统波束 形成法、Bartlett波束形成法、Capon波束形成法的空间谱图。(7-element linear antenna array (ULA) Known: the signal center wavelength is 2, the antenna element spacing of 1 m, the number of snapshots for 2000, the air there are four Source signal, assuming that their frequency: 0.015, 0.05, 0.02, 0.035 The direction of the four source signals: pi/4 pi/3 pi/6 3pi/4 Requirements: 1) not to join the noise, to draw the traditional beam-forming method, Bartlett, beam Formation method, Capon beamforming method of the space spectrum 2) by adding Gaussian white noise, assuming that the SNR is 10dB, to draw the traditional beam Formation method, Bartlett, beamforming, Capon beamforming method of the space spectrum.)

用matlab仿真，得到较为真实的飞行航迹，包括了转弯，机动等轨迹运动模型的描述(Matlab simulation used by more real flight track, including a turn and the track motor sports, such as a description of the model)

说明：  1. 编程实现图像傅立叶高通、低通滤波。 2. 尝试傅立叶压缩。 (1. Programming image Fourier high-pass, low pass filtering. 2. Try Fourier compression.)

二维 有限元 三角形 插值积分 很不错(Dimensional finite element triangle Quadratures very good)

kalman滤波matlab程序，利用双点差分外推法取初值，并多次求平均值(kalman filter matlab procedures, the use of two-point difference extrapolation to take initial and repeated averaging)

Independent component analysis for face recognition

计算正弦信号apFFT数字全相位信号谱，并把图形画出可视化(Calculated sinusoidal signal apFFT digital, full-phase signal spectrum, and to draw graphical visualization)
