how to call libKriging in C++

[manuel76413]

I write a c++ demo program, but the prediction value is much different than origin value when use gauss kernel,
give me some advices, how to use this library .

Kriging ok = Kriging(y,X,"gauss");
auto ans = ok.predict(X1, true, true, true);
arma::Col prearray = std::get<0>(and);

but when I changed to matern3_2 the predict value is correct, tha't why?

Hi. yes, it sounds strange...
Can you give some more details : dimension of X (be careful that for 1D, "gauss" is not recommended).
You can also provide example with Python (quite same syntax).
