finding mimima in array of noisy data by curve fitting??

[Matt P]

I need to located a global minima in an array though some local minima may happen to be below this value due to noise. The data should be nearly parabolic. Can anyone suggest a way to find this minima the most efficiently using labview?

Just fit the area of interest to a polynominal, then get the minimum of the fit. see attached code. (LV6.1).
