说明：  draw a signal with its envelope

灰色系统的源代码，可以进行短期预测，对比现实数据，得出某因素的影响(The gray system source code, can undertake short-term prediction, )

Crystal Clear SSI for Operational Modal Analysis

输入自己事先录制好的语音信号，该程序实现将语音信号通过FIR低通、高通、带通滤波器后还原出来的语音质量(Enter their own pre-recorded speech signal, the program will realize voice signal through the FIR low-pass, high pass, band-pass filter to restore them after the voice quality)

MATLAB simulation of group velocity dispersion in an optical fiber

说明：  针对单帧图像进行POCS处理，实现图像的潮分辨率(POCS for single frame image processing, the tide of image resolution)

this test checks the value of Number.

数字信号处理实验内容，编写能够实现fft的matlab程序，并与系统自带的fft相比较。在文件mysecond.m中注释部分给出多种fft实现方法及代码，未拆分成多个m文件(Digital signal processing experiment content, the preparation can be achieved fft matlab program, and compared with the system comes with the fft. The comment section file mysecond.m give multiple fft to achieve method and code into multiple m 未拆)

计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)

MATLAB自已编的二维DLA，基于ORL人脸数据库，效果不错。(MATLAB own series of two-dimensional DLA, based on the ORL face database, good results.)
