Fit smoothing splines in Curve Fitting app or with
the fit
function to create a smooth curve through
data and specify the smoothness.
Fit smooth surfaces to your data in Curve Fitting
app or with the fit
function using Lowess models.
Use the smooth
function to smooth
response data, using methods for moving average, Savitzky-Golay filters,
and local regression with and without weights and robustness (lowess
, loess
, rlowess
and rloess
).
Fit Smooth Surfaces To Investigate Fuel Efficiency
This example shows how to use Curve Fitting Toolbox™ to fit a response surface to some automotive data to investigate fuel efficiency.
Nonparametric fitting to create smooth curves or surfaces through your data with interpolants and smoothing splines.
