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-Test program to create a time to compare the Formula Node and the local LabVIEW average execution time of mathematical functions. For this program requires a loop or a flat or stacked sequence structure and sequence of a Case structure. For cycle time required to run tests N times, then use the Statistics Express VI do the results mean. Order structure of the code required to run the code to run before and after the sampling of the Tick Count. Case structure, the user is required to execute the formula to determine the node or to the local LabVIEW implementation of mathematical functions. Running time for each branch test program. Which method is the fastest execution time? Which method is the most easy to program? Others depend on procedures, which method is easier to understand
