Labview的EXCEL工具包和实例，几乎包括了所有关于EXCEL的操作，可以作为学习和实际应用的参考(EXCEL toolkits and examples of Labview, including almost all operations on EXCEL can be used as reference for study and practical application)

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)

利用Matlab的图象处理功能对摄象头采集到的仪表图象进行分析,得到指示值,同时利用dll 技术,在虚拟仪器编程软件Labview 中调用,输出得到对应的计算值,实现了对指针式仪表的自动监控,增加了整个系统的稳定性和可靠性。(Using Matlab image processing functions on the image pickup head collected instrument image analysis, to give the instruction value, while using dll technology, called the virtual instrument programming software LabVIEW, obtained from the output corresponding to the calculated value, the pointer Instrumentation automatic monitoring, increasing the stability and reliability of the whole system.)

LABVIEW求数组的N个元素的滑动平均值(LABVIEW find moving average of N elements of the array)

说明：  利用labview做数学公式调用dll,亲测好使(Using LabVIEW to make mathematical formulas to call DLL)

说明：  labview实现了多通道串口数据的TDMS保存(LabVIEW realizes TDMS saving of multi-channel serial port data)

该程序基于labview2012研发，利用希尔伯特变换实现提取信号的包络。一部分是对AM信号的仿真实验，另一部分是其通用形式，只需拷贝到自己的引用程序中即可。(The program is based on the labview2012 , the use of the Hilbert transform to extract the signal envelope. Part of the AM signal simulation, another part is in its generic form, can be simply copied to the reference program.)

利用Labview编写的画圆程序，小巧实用，确定半径和圆心即可(Circle program written with Labview, compact and practical)
