I have a dataset represented by table obtained from FE Analyses for flux linkage and i want to process this raw data into proper format through MATLAB scripting (as Look up table), where this raw data conaines parametric sweep
I would like to convert this 4-Colomn table into gridded data set in form of 3D Aarry v=(x,y,z), where x,y,z are the first three colomns and the last colomn is v. then i want to process the data with 'griddedInterpolant' to get finer gidded data. The complete dataset provides all of the information needed to create a gridded data set.

x=unique(t{:,1}); nx=numel(x);
y=unique(t{:,2}); ny=numel(y);
z=unique(t{:,3}); nz=numel(z);
v=permute( reshape(t{:,4},[ny,nx,nz]) ,[2,1,3]);
F=griddedInterpolant({x,y,z}, v)

It will work, but you will need,
v=permute( reshape(t{:,4},[nx,nz,ny]) ,[1,3,2]);
since now the y-coordinate varies the slowest.
