How to window peak structures from a 1D array with frequency drift

[caz]

I have a huge 1D array that I would like to find the location of a repetitive peak. The peakfinder.vi can't handle the whole array so I need to window the array in a for loop to isolate one peak at a time. The problem is the frequency of the peak drifts throughout the array so I need an adaptive array subset function

Have you tried using the peak detector.vi? It comes with LabVIEW full.

Peak detector.vi won't handle the whole array at once. The array has 36E6 elements in it and the peak detector chokes up when dealing with the entire array at once
