Does Matlab provide the predicted R-squared value?

In Regression analysis the predictied R-Squared value gives information regarding overfittting and prediction of a model. This information is additional to the adjusted R-Squared value. However I can not find a Matlab function that provides the Predicted R-Squared value (Neither in the Curve fitting toolbox nor in the statistical toolbox)!

I found a workaround for this issue:
Then:
lm = fitlm(X,'Y~x1+x2)
pr = press(X)
rPred = 1-pr/lm.SST
