Show us the code which lead this error.

Answer 1

[Valeria Leto]

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

Answer 2

[Walter Roberson]

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()
