converting array data

I capture a signal into an array of 512 data points that I would like to convert
to 360 data points without losing much of the information in the signal.
Has anyone ever done anything like this? Any ideas on how to do it? Thanks!

Other than just taking the first 360 points, the only suggestion I have is to
use the array you have and generate an nth order polynomial that represents
your signal, and then output 360 points at intervals and derive your 360
element array in that manner.

Checkout the "Interpolate 1D array" and perhaps "Threshold 1D array"
functions on the "Array" palette. Much less hassle.
