C#编写的上位机，可实现串口数据收发，功能强大，界面优美(C# compiled host computer, can realize serial port data receiving and receiving, powerful, beautiful interface)

竞争性自适应重加权算法（CARS）是通过自适应重加权采样（ARS）技术选择出PLS模型中回归系数绝对值大的波长点，去掉权重小的波长点，利用交互验证选出RMSECV指最低的子集，可有效寻出最优变量组合。(Competitive adaptive reweighted algorithm (CARS) is obtained by adaptive reweighted sampling (ARS) technique is selected in the PLS model regression coefficients with large absolute values of wavelength, remove the weight of small wavelength, using cross validation to select the RMSECV refers to the minimum subset, can effectively find out the optimal combination of variables.)

机械仿真建模，可用于实现真实模型的逼真建模，便于与MATLAB展开联合仿真(Mechanical simulation modeling)

创建一个计时测试程序，比较公式节点和本地LabVIEW数学函数的平均执行时间。此程序需要一个For循环或一个平序或叠序结构以及一个Case结构。要求For循环运行计时测验N次，然后使用Statistics Express VI对结果做平均。要求顺序结构在代码运行之前以及代码运行之后对Tick Count进行采样。要求Case结构判定用户是要执行公式节点还是要执行本地LabVIEW数学函数。对每个分支运行计时测验程序。哪种方法执行时间最快？哪种方法最容易编程？别人要看程序时，哪种方法更容易理解？(Create a timing test program to compare the average execution time of formula nodes and local LabVIEW mathematical functions. This program needs a For loop or a plain or overlapping structure and a Case structure. Require the For cycle to run the timing test N times, and then use Statistics Express VI to average the results. The sequential structure is required to sample Tick Count before and after the code runs. The case structure is required to determine whether the user wants to execute formula nodes or local LabVIEW mathematical functions. Run the timing test program for each branch.)
