Alejandro - while I would like to implement that capability one day in the future, that day may be a long time away before I find the time. Until then, all I can offer is to use a finer grid, which will mimic a higher order interpolant.
Dominik - Sorry, but no. You could use this tool to generate a gridded surface, then use interp2, to interpolate, but that is perhaps too much if you only wanted to interpolate a few scattered points.
Hey
i wonder, can this code also be used like an interpolant (e.g. gridded interpolant), i.e. such that the output is not the smooth funtion on a grid, but on certain points queried?
Great function!
I was just wondering: would it be difficult to extend it for a cubic interpolation? (it was mentioned in the code as a future enhancement).
