@KSSV I can't load the matrix because the files are too big even in a .zip format

We cannot tell what length(u) or length(v) or size(Xq) or size(Yq) is.
You could get an error if size(Xq) is not the same as size(Yq) or size(Zq) or size(V_1)
for i=1:1:length(v)
V_1(i,:)=vq_1(1+(i-1)*length(u):1+(i-1)*length(u)+(length(u)-1),1)';
end
I suspect that could be written as
V_1 = reshape(vq_1, size(Xq));
I speculate that some values of vq_1 are NaN because you did not ask for extrapolation in the griddata()
