Put these two files into the same directory and run mariosong.m. It will play the first part of the mario brothers theme song. You can edit note.m to add qualities to the sound

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)

MATLAB编程可计算吸收率电导率等公式，对石墨烯计算和拟合分析很有帮助(The fitting of computable absorptivity in MATLAB programming)

一个简单的CA模型，用于仿真实践，使初学者很容易接受，简单易懂(A simple CA model, for the simulation of practice, so that beginners are easy to accept, easy to understand)

采用AR法模拟风速，计算时间较短，但精度相对于谐波叠加法略差(AR method using simulated wind speed, the calculation time is shorter, but the accuracy is slightly worse relative to the harmonic superposition)

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)

由于小波函数没有显示表达，此程序通过数值方法将其表示出来(wavelet function)
