Fitting is a common task when analyzing measured data. This involves finding a formula that best describes the relationship between one or more independent variables to a dependent variable. Good initial estimates of the independent variables are critical to achieving a good fit in reasonable time but this can be difficult to achieve, especially if the data is noisy.
WE-FIT by Wakefield Engineering is an add-on fitting package for LabVIEW that does the hard work of initial estimation for you. The free version makes it very easy to fit to some commonly used functions including Gaussian, Super Gaussian, Extreme, Boltzmann, Sine, Exponential Growth and Lorentzian.
