说明：  模拟退火的实现代码，给出具体的案例分析。可以按照不同需要对程序体进行改进(The realization of simulated annealing code, gives specific case studies. According to the different needs of the program to improve body)

信号与系统软件实验工具箱，本系统包括七个实验，分别是：信号的时域基本运算、连续信号的卷积与连续时间系统的时域分析、离散信号的卷积与离散时间系统的时域分析、信号的频域分析、连续信号的采样与恢复、系统的频域分析、信号的幅度调制与解调。为了加强学生的计算机编程能力和应用能力，所有实验均提供设计性实验内容，让学生参与编程。本系统既可作为教师教学的实验演示，又可作为学生动手实验的实验系统。(Signals and Systems Software experimental toolbox, the system includes seven experiments, namely: basic operations signals in time domain, the convolution of continuous signals and continuous-time system time domain analysis, convolution of discrete signals and discrete-time systems when domain analysis, frequency domain signal analysis, continuous signal sampling and recovery, system frequency domain analysis, signal amplitude modulation and demodulation. In order to strengthen the student s computer programming skills and ability to provide all the experiments were designed experiment content, allowing students to participate in programming. This system can be used as experimental demonstration of teaching, but also as a student hands-on experiments the experimental system.)

说明：  算法是基于灰狼优化算法GWO优化VMD，可以大大提高VMD的分类准确率，提高优化时间。(This algorithm is based on GWO optimization VMD, which can greatly improve VMD classification accuracy and optimization time.)

Script originally intended for use in oceanography/fluid dynamics. Use: >> ipdv(X,Y) (0,0) default initial position or >> ipdv(X,Y,Xo,Yo) (Xo,Yo) initial position 2D vector components (X,Y) are used to plot the vectors one after another, i.e., next vector starting at the end of the previous one (via Matlab s quiver.m ). This function handles NANs (Not-A-Number) by putting Zeros in their place, thus allowing the Matlab cumsum.m function to compute the progressive positions (Matlab function cumsum.m doesn t skip Nans). NaNs produce discontinuities in the graphic.

fir滤波器，7、8、13、14，对信号进行alpha、betagamma滤波，调用方法 Hd = fir_alpha 滤波后信号 = filter(Hd,原信号) 得到的信号是时域信号，plot直接显示(Fir filter, 7, 8, 13, 14, alpha filter for signal method is called Hd = fir_alpha After filtering signal = filter (Hd, the original signal) Signal is time domain signals, the plot showed directly)

基于BP网络预测的matlab程序，可以用于BP网络预测，matlab编译通过(BP network based on the forecast matlab procedures, can be used in BP network prediction, matlab compiler through)

mathlab的三个分别灰色绝对关联度，相对关联度，归一关联度的代码，是三份M文件(mathlab absolute correlation of the three were gray, relative correlation, normalized correlation of the code, the file is three M)
