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

interpolation is a method of estimating values between known data points. use interpolation to smooth observed data, fill in missing data, and make predictions. curve fitting toolbox™ functions allow you to perform interpolation by fitting a curve or surface to the data.

to interactively fit an interpolating curve or surface, use the curve fitter app. fit an interpolating curve or surface at the command line by using the fit function. for more information, see interpolation with curve fitting toolbox.

topics

  • interpolation with curve fitting toolbox

    apply interpolation methods to estimate values between known data points for curves and surfaces.


  • extrapolation is a process for estimating dependent variable values for independent variable values outside of the fitting data domain.


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