Hi all,
I am trying to find a way to calculate the standard deviation of any point I want from a GPR model.
Function handle for predicted response works, but not for predicted standard deviations and I get the error 'Only functions can return multiple values'
Trust all clear
Thanks
gprMd1=fitrgp(x_train,y_train);
[yFit,ySD,yInt]=predict(gprMd1,x_test)
YFit=@(x) predict(gprMd1,x)
[~,YSD]=@(x) predict(gprMd1,x)

请先登录，再回答此问题。

yes，sir，may be use function file，such as
function ysd=spredict(gprMdl,x)
[~,ysd] = predict(gprMdl,x)
