array of 15 elements: with every measurement delete first element and append actual value

[steffi.kono]

Hi everybody,

I would like to analyze my measurements in realtime as I control a device with the results of the analysis.

Therefor I would like to continuously calculate the mean value of the last 15 values.

I know how to create the array of the first 15 elements, but how can I (after I got the first 15 values and calculated the first mean value of them) delete the first value and append the actual value with every following step? I tried it with the "Replace Array Subset", but it doesn't work the way I do it: (. Can I do all these steps within one while loop?

I think it's not that difficult, but I don't know any solution right now: ( I would really appreciate anybody's help or a simple example, I work with LV 8.0.

Thank you very much in advance.

Hi steffi,

you can use the "Rotate 1D Array" vi. See the attached example.

This is just another method.

Steffi,

I posted a circular buffer example using queues on your other thread.

Yet another method. This uses one of the Point-by-Point functions (see attached images)

Hi Steffi,

this will work without any shifting of elements in memory:
