5-data average Mean PtByPt works

[knowlittle]

I have a 1-D array of 500 numbers. I would like to use average of 5 data points. I found an example of Mean PtByPt in a loop. But nothing is connected to "i" and "N" inside the loop. Does the vi take care of "i" and "N" based on user input (500 elements and 5-data average)? How many elements are there in the output array? Thank you.

Hi little,

it would help to see your example of MeanPtByPt.

I'm using the PtByPt function coming with LabVIEW:

So nothing is connected to "i" or "N". Thank you. I am still not clear about the output array. Regarding the first element of the output array, is it the average of first 5 data points? What about the last element of the output array? Please explain these to me. Thank you.

Autoindexing Tunnels is a very basic concept in LabVIEW.  I highly recommend you take some of the free online tutorials.

In short, the FOR loop will iterate on the input array and will iterate once for each element in the array.

Thank you for the links. I will take those courses.
