Hi,
I have a database with columns of latitude, longitude, time and a variable. I want to interpolate that variable to the latitude, longitude and time of another database. How can I do that?

T = readtable('EXAMPLE_DATA.xlsx') ;
X = T.X ;
Y = T.Y ;
Z = T.Z ;
V = T.V ;
Xq = T.Xq ;
Yq = T.Yq ;
Zq = T.Zq ;
% Vq = griddata(X,Y,Z,V,Xq,Yq,Zq) ;
F = scatteredInterpolant(X,Y,Z,V,'nearest') ;
Vq = F(Xq,Yq,Zq) ;
scatter3(X,Y,Z,[],V,'h','filled')
colorbar
figure
scatter3(Xq,Yq,Zq,[],Vq,'h','filled')
