经常看到很多朋友问定步长的龙格库塔法设置问题，下面吧定步长四阶龙格库塔程序贴出来，有需要的可以看看 (Often see many of my friends ask determining step Runge-Kutta method set problem, the following step you set the fourth-order Runge-Kutta procedures paste out, there is a need to look at the)

Creat a signal with white noise

用MATLAB编写与仿真了MSK信号，其中结合了自己写的快速傅立叶变换实现了MSK信号的调制还有解调，而且作为拓展，还加入噪声、通过带通滤波器、低通滤波器、载波信号等等。调制解调都很有用，画出的图也很漂亮规范。(Using MATLAB and the simulation of the MSK signal, which combines the fast Fourier transform to write their own modulation there demodulation of MSK signals, but also as a development, but also by adding noise, band-pass filter, low pass filter, the carrier signaland so on. The modem is very useful to draw the plan is also very beautiful and specification.)

apriori算法，用MATLAB写的。 不是本人所写，但感觉写得不错，特与大家分享 (I have not written, but the feeling is well written, special to share with you)
