Can I use different models to do a 2D fit?

Hello everyone. I am currently working in a two-dimensional interpolation.
I can write
sfX = fit([positions(:,1), positions(:,2)],windX_in_the_node_vector,'poly34')
witout any issue. However, if I check the documentation, I see that the only other surface fit that can be used is 'lowess'. Is this true or can I use splines or other alternative interpolation methodologies?
Best regards.

Yes, but you don't need the Curve Fitting Toolbox just tod surface interpolation. With interp2 (if you have gridded data) you can use any of the ones listed here,
If you have scattered samples, then with griddata, you can use any of the methods here,
