快速傅里叶变换和小波包能量提取代码，可以对采集到的信号进行预处理。(Fast Fourier transform and wavelet packet energy code, can be collected signal preprocessing.)

说明：  涡旋光束在光束的传播方向上有一个位相项e，而且它拥有一个光束轨道角动量，该matlab程序实现了从一个高斯基模变换到涡旋光束的基本功能。(The vortex beam has a phase term E in the direction of beam propagation, and it has a beam orbit angular momentum. The matlab program realizes the basic function of transforming from a Gaussian fundamental mode to a vortex beam.)

说明：  各种神经网络设计的源码，通过MATLAB验证 (The source of various neural network design, verification by MATLAB)

给出一段噪声音乐信号，用滑动平均滤波器进行处理，观察改变滑动窗口宽度对声音效果的影响。 （1）读取一段噪声信号，画出未处理噪声信号的时域波形和信号频谱图； （2）在Matlab中利用滑动平均滤波器对噪声信号进行处理，得出处理后的图像； （3）改变滑动窗口的宽度，观察处理后噪声以及图像得出对效果的影响。(A piece of noise music signal is given. It is processed with a sliding average filter to observe the effect of changing the width of sliding window to the sound effect. (1) a noise signal is read and the time domain waveform and signal spectrum map of the unprocessed noise signal are drawn. (2) in Matlab, a sliding mean filter is used to process the noise signal, and the image after processing is obtained. (3) to change the width of the sliding window, to observe the noise after processing and to the effect of the image.)

Define two fuzzy numbers with any MF type I and J by using your own intuition. Choose one of the arithmetic operator (∗ ={+,− ,×,÷}) and use extension principle to calculate I∗ J by using MATLAB.
