sfit
Constructor for sfit
object
Description
constructs the surfacefit
= sfit(fittype
,coeff1,...,coeffn
)sfit
object surfacefit
using the model type specified by the fittype
object and the
coefficient values coeff1
, coeff2
,
etc.
An sfit
object encapsulates the result of fitting a surface
to data. They are normally constructed by calling the fit
function, or interactively by exporting a fit from the Curve Fitter app to the
workspace. You can get and set coefficient properties of the
sfit
object.
You can treat an sfit
object as a function to make
predictions or evaluate the surface at values of X and Y.
Like the cfit
class, sfit
inherits all
fittype
methods.
Note
sfit
is called by the fit
function when
fitting fittype
objects to data. To create an
sfit
object that is the result of a regression,
use fit
.
You should call sfit
directly only if you want to
assign values to coefficients and problem parameters of a
fittype
object without
performing a fit.
