The "PP" form for N-dimensional Interpolation with cubic splines
I am trying to do N-dimensional interpolation for a dataset defined over
5-dimension regular grid. I want to use cubic spline.
I believe that the function I want to use is "interpn" with method ==
Is it possible to obtain the "pp" form of the spline with the "interpn"
This option is valid only for "interp1" function as: pp = interp1 (…, "pp")
but it is not available for "interpn". Is there any work around?
