Curve Fitting Toolset™

EZL’s Curve Fitting Toolset™ computes the best-fitting curve to a given set of points by least squares polynomial equations. It is easy to use and provides fast results.

Ill-conditioned data are handled by pre-removing the mean of the independent variable before computing an LU decomposition. This results in numerically accurate curve fits, even for high orders models.

Curve Fitting Features:

EZL’s curve fitting software provides quick access to the two primary operations, Detrend and Model. For each operation, the curve fitting software provides quick access to:

• Linear — 1^st order fit
• Quadratic — 2^nd order fit
• Cubic — 3^rd order fit
• Poly — n^th order fit (you specify!)
