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?
