HS_VaR_Backtest

PCA数据降维，利用MATLAB进行开发学习(PCA of data dimensionality reduction, using MATLAB to develop learning)

overall heat transfer

压缩感知OMP算法实现一维信号和二维图像重构(Orthogonal Matching Pursuit Algorithm for Signal Reconstruction Based on Compressive Sensing)

convex spectral clustering

VMD变分模态分解，vmd函数是通用的，vmd_test是1s专用的，所以只要改test文件，要设一个时间(VMD variable modal decomposition, vmd function is universal, vmd_test is dedicated to 1s, so just change the test file, set a time)

对如下可靠性问题进行仿真 现在有两种方案：方案一是损坏一个更换一个；方案二是一旦有轴承损坏就全部更换．试通过计算机仿真对这两种方案做出评价．(The following issues on the reliability of simulation now there are two programs: a program to replace a damaged one program Second, once all the replacement of damaged bearings. Examination by computer simulation to assess the two programs.)

hht_toolbox工具箱用 时频分析必备 大家共同学习(HHT toolbox for HHT time-frequency analysis )

该程序为萤火虫算法matlab源代码，不包含问题、编码、解码等部分，只是单纯的运算方式。可在此基础上继续编写子程序，解决具体问题。(This program is the firefly algorithm matlab source code, does not contain problems, coding, decoding and other parts, just a simple operation. On this basis, you can continue to write subroutines to solve specific problems.)

对pam调制的误码率进行理论和仿真对比，用的是蒙特卡罗方法(01:15 modulation of the BER and the theoretical simulations, using the Monte Carlo method)
