本程序能够产生ami码，并且能够绘制其波形图和功率谱密度图(This procedure can produce ami code, and can draw their waveforms and power spectral density map)

用MATLAB实现快速傅里叶变换。方程有需要的话，可以自己设定(Using MATLAB to achieve fast Fourier transform. Equation there is a need, they can set their own)

声波模拟的去频散程序，能有效减少频散效应。。。。(Dispersion modeling to the sound process, can effectively reduce the frequency dispersion effect. . . .)

Z=X+Y 求Z的分布 並且畫出圖 並與理論公式值做比較 (Z = X+ Y seeking to draw the map the distribution of Z and compare with the theoretical formula for the value)

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (Themohu function is used in mainly control applications. PIDCalc performs one iteration of the PID algorithm. While the PID function works, main is just a dummy program showing a typical usage.)

Bernstein基函数的matlab代码(failed to translate)

在matlab 下的自适应中值滤波。可以处理彩色图像( matlab colorpicture zhongzhilvbo)

在傅立叶变换光学中夫琅和费衍射场的强度分布就等于屏函数的功率谱。因此我们可以直接将光屏进行傅立叶变换，再处理得到衍射图样。(In the Fourier transform optics, Fraunhofer diffraction field intensity distribution is equivalent to the power spectrum display function. Therefore, we can directly Guangping Fourier transform, and then to handle any diffraction pattern.)

混沌系统的吸引子，很简单，初步学习可以看看(Attractor of the chaotic system is very simple, the initial learning can take a look at)

时间序列分析的工具箱,里面有html说明(time series analysis toolkit, which has html note)
