Function handle for standard deviation of a GPR

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)

yes，sir，may be use function file，such as

function ysd=spredict(gprMdl,x)
[~,ysd] = predict(gprMdl,x)
