Interpolate N-D scattered data

It is not practical to use

`griddatan`

for interpolation in dimensions higher than about 6-D, because the memory required by the underlying triangulation grows exponentially with the number of dimensions.Scattered data interpolation with

`griddatan`

uses a Delaunay triangulation of the data, so can be sensitive to scaling issues in`x`

. When this occurs, you can use`normalize`

to rescale the data and improve the results. See Normalize Data with Differing Magnitudes for more information.
