interpolation 3+ variables and a datavector..

Hi all I really need some help, with this little problem. :-)

I simply just need a way to make a linear/cubic interpolation in 3+ data variables (x,y,z,...) and get a interpolated result from another vector (r)

I've tried interpn and griddatan, but i couldn't get it to work..

lookup_point=[0.65,1,0.03]

x = 0.6000 0.2000 0.3000 0.5000 0.3000 0.6000 0.7000

y = 2 2 3 1 1 1 1

z = 0.1500 0.0200 0.0200 0.0300 0.0300 0.0200 0.0500

r = 222 333 442 324 532 100 200

%Data
x = [0.6000 0.2000 0.3000 0.5000 0.3000 0.6000 0.7000]
y = [2 2 3 1 1 1 1]
z = [0.1500 0.0200 0.0200 0.0300 0.0300 0.0200 0.0500]
r = [222 333 442 324 532 100 200]
lookup_point=[0.65,1,0.03]

% Build interpolant
SI = scatteredInterpolant(x',y',z',r')
SI(lookup_point) %use it

Nice! What if I would like a cubic interpolation?
