说明：  差分演化模板程序,matlab函数优化。(Differential evolution template program, matlab function optimization.)

VMD方法是在传统维纳滤波的基础上，提出的一种非递归自适应信号分解新方法。与EMD方法和LMD方法相比，VMD方法分解的信号，具有精度高、收敛快和鲁棒性好等特点，适用于处理滚动轴承故障信号。(The VMD method is a new non recursive adaptive signal decomposition method based on traditional Wiener filtering. Compared with the EMD method and the LMD method, the signal decomposed by the VMD method has the characteristics of high precision, fast convergence and good robustness. It is suitable for handling the fault signal of rolling bearing.)

说明：  产生正弦波、均匀白噪声、高斯白噪声图形；利用小波变换去噪并求信噪比。(Sine wave, uniform white noise and Gauss white noise are generated; wavelet transform is used to denoise and SNR is calculated.)

一本很好的matlab学习书籍，综合了很多的内容，英文版的，对英文又要求( Matlab learning good book, synthesized a lot of content, the English )

operating systems introduction what operating systems do computer-system organization computer-system structure computer-system architecture

有限元程序的matlab工具包，用于各种不同有限单元的划分，力和响应的计算等(Matlab finite element procedure kits for a variety of finite element division and the calculation of response)

已知轴线方程,把圆柱按轴线分若干段，在每个断面画圆，圆的法线就轴线的切向方向。柱面画若干平行于轴线的线条，其中用到平行单位矢量点积等于1，不平行的结果是[-1，1）。 (Axis equations are known, according to the axis of the cylinder divided into several segments, each section in the circle, the circle axis normal to the tangential direction. Number of cylinders parallel to the axis of drawing lines, which use the parallel unit vector dot product is equal to 1, the result is not parallel to [-1,1). )
