That is, what I try now. But the fields are very large (75.000 points). Can you give me a hint, how to interpolate from grid (from giddata3) to points?

 

Thanks!!

griddata3 can interpolate directly from one set of scattered points to another. E.g.

n = 1000;

m = 1200;

X = randn(n, 3);

Y = randn(m, 3);

v = X(:, 1) + X(:, 2) + sin(X(:, 3));

w = griddata3 (X(:, 1), X(:, 2), X(:, 3), v, Y(:, 1), Y(:, 2), Y(:, 3));
