2d-spline interpolation with scattered data?

hi forum,

i have scattered data and i used to extrapolate these to the area-borders (glacier-borders) with gridfit from the fe (bilinear interpolation) and it works great.

a colleague did a spline interpolation with the same dataset in arcgis. in matlab spline-interpolation is only available for gridded data (interp2, griddedinterpolant).

is there a possibility to do a 2d-spline interpolation with scattered data in matlab?
