实验4-微分方程

matlab的一本很好的资料，含有大量实例，及程序源码(matlab a good information, contains a lot of examples, and program source code)

基于等均值等方差的图象矢量量化Matlab程序(Based on the mean variance of the image, such as vector quantization Matlab procedures)

说明：  讲述了Matlab中小波降噪技术的使用，并讲述小波分解原理及如何检验。(Tells Matlab to use the wavelet noise reduction technology, and wavelet theory, and how about the test.)

a matlab code for alnalysing the faults

This is used for contrast streching in an image to improve the image quality.

产生线性调频信号，并进行时域压缩和频域压缩(Have a linear FM signal, and compressed time-domain and frequency domain compression)

simulink双效串并联吸收式制冷动态仿真(simulation for absorption refrigeration)

本例程是利用MATLAB作为开发工具，编写代码实现卷积的数值运算(This routine is to use MATLAB as a development tool to write code to achieve the numerical convolution of)

说明：  随机森林算法程序，用于对数据的仿真预测，是一个有用的算法(Random forest algorithm program)

说明：  对信号进行频域特征提取，先通过傅里叶变换得到信号频谱，再计算频谱特征，包括重心频率，均方频率和频率方差(Firstly, the frequency spectrum of the signal is obtained by Fourier transform, and then the spectrum characteristics, including center of gravity frequency, mean square frequency and frequency variance, are calculated.)
