Interpolation 20 variabels and 10000 datapoints? - SOS!

Hi all I have a growing csv file with 150+ rows with 20 variables and 10.000 datapoints.

a row: var1 var2 ... var20 data1 data2 ... data10.000

lookup (20 vars.): 5.5 5.0 3.0 1.0 1.0 0.8 0.0 0.3 0.05 0.05 0.7 0.2 0.7 0.7 0.7 0.0 0.0 0.0 0.0 0.0

I have attached the csv file..

I have tried scatteredInterpolant, griddatan and interpn nothing seems to work, perhaps i'm doing something wrong. (trial and error hehe)

It would be nice to be able to choose between linear interpolation and some kind of nonlinear interpolation e.g. cubic :-)

You didn't attach anything - no m-file and no csv file. Be sure to click the "Attach file" button.

Griddatan seems to do the job, if I first remove all rows with identical data. If anybody have a way to make a nonlinear interpolation I would really be grateful :-D
