Interpolation

Fit interpolating curves or surfaces, estimate values between known data points

Apps

Curve Fitting

Fit curves and surfaces to data

Functions

`fit`	Fit curve or surface to data
`fittype`	Fit type for curve and surface fitting
`fitoptions`	Create or modify fit options object
`get`	Get fit options structure property names and values
`set`	Assign values in fit options structure
`feval`	Evaluate cfit, sfit, or fittype object
`prepareCurveData`	Prepare data inputs for curve fitting
`prepareSurfaceData`	Prepare data inputs for surface fitting
`excludedata`	Exclude data from fit

Topics

Selecting an Interpolant Fit

Fit interpolant models in Curve Fitting app or with the fit function.

Interpolation Methods

Interpolation methods for estimating values between known data points for curves and surfaces.

Nonparametric Fitting

Nonparametric fitting to create smooth curves or surfaces through your data with interpolants and smoothing splines.
