Performs linear interpolation on a scattered dataset within the convex hull of the dataset. Extrapolates by holding the nearest point on the edge of the convex hull. Avoiding the discontinuity at the convex hull that occurs when calling the scatteredInterpolant function with "linear" interpolation and "nearest" extrapolation options.
As always, consider scaling the input coordinates if appropriate.

As of R2024a, use scatteredInterpolant with "boundary" as the extrapolation option. This submission may still be helpful if you need this behavior in earlier versions of MatLab.
