本程序可以产生LFM信号，经过实验验证，程序正确，可以执行，改变参数即可得到你想要的图形(produce a LFM signal)

通过此代码，实现MSK调制。模拟基带信号频率为1kHz，正弦载波信号频率为6kHz。(MSK MODULATION)

T型尾翼颤振进计算。结合了nastran生成的模态坐标f06文件及气弹计算软件ZAERO。片条法计算非定常气动力里面的定常附加部分。(T-tail flutter ansys, composite of f06 and ZAERO.)

说明：  scpwm 空间矢量控制 仿真软件matlab 学习pwm有价值(scpwm space vector pwm control of a valuable learning simulation software matlab)

This code is face localization programme. It reads faces from yale database and localize the face in the image.

电动汽车燃料电池simulink仿真模型，用于电动汽车或者混合动力汽车的仿真模型(Simulink simulation model of the electric vehicles fuel cells for electric vehicle or hybrid vehicle simulation model)

基于OFDM信道冲击响应和信道估计的matlaB仿真代码。值得借鉴！(Based on OFDM channel impulse response and channel estimation matlaB simulation code. Worth learning!)

可以读入.mav格式的音频文件，同时可以仿真出此音频文件的时域及频域的波形图，加入噪声后，可以仿真出加噪后的音频时域及频域波形，并保存新的音频文件。(Mav format audio files that can be read into simulation time domain and frequency domain waveform diagram of audio file, you can add noise simulation time domain and frequency domain waveform plus noise audio, and save the new audio files.)

自己编写的简单流体力学程序，供大家参考学习(Hydrodynamics code to write your own simple, for your reference learning)
