How to get the equation of a non parametric curve fit onto a data?

Hi, I would like to know if its possible in matlab to get the equation of the lowess or spline filter's equation. This equation i would like to further apply to predict my test data.

Hi,

The Curve Fitting toolbox has several nonparametric fitting options, including:

• Interpolation Methods
• Smoothing Splines
• Lowess Smoothing

Here is an article about Lowess Smoothing in MATLAB.
