the following scrpt creates this plot:
load('var.mat')
scatter3(xq(:),yq(:),zq(:),2,'k','filled'); hold on
scatter3(x,y,z,10,'r','filled')
From the data, you can see that xq,yq,zq and cq are a gridded data.
I want to use griddedInterpolant function to "fill" the cq(which contains NaN) values inside to x,y,z,c positions with an interpolation of c info. and remain all the points "outside" the red points as NaN.

load('var.mat') ;
scatter3(xq(:),yq(:),zq(:),2,'k','filled'); hold on
scatter3(x,y,z,10,'r','filled')
F = scatteredInterpolant(x,y,z,c,'nearest') ;
cq0 = cq ;
for i = 1:583
i
cq(:,:,i) = F(xq(:,:,i),yq(:,:,i),zq(:,:,i)) ;
end

Read the document......you have an option to play around with that..you need to use Extrapolation method to none.
