uqlab  
X1 = Xmodelouhe{p}(:,1);  
X2 = Xmodelouhe{p}(:,2);  
Y1 = Ymodelouhe{p};  
Xuse = [X1,X2];  
Yuse = Y1;  
MetaOpts.Type = ‘Metamodel’;  
MetaOpts.ExpDesign.Sampling = ‘User’;  
MetaOpts.MetaType = ‘Kriging’;  
MetaOpts.Trend.Type = ‘ordinary’;  
% MetaOpts.Input = myInput;  
MetaOpts.ExpDesign.X = Xuse;  
MetaOpts.ExpDesign.Y = Yuse;  
x0 = mean([min(Xuse); max(Xuse)]);  
yKrigingF{p+m} = uq\_createModel(MetaOpts);  
it seens that it cant work

Dear @hanyu

To me, this looks more like an incorrect use of Matlab than a problem with UQLab. Unfortunately, I can’t help you without knowing what `Ymodelouhe` and `Xmodelouhe` are. Can you provide an executable example?

Best regards
