How to generate partial dependence plots (PDP) in boosted regression trees with fitensemble (LSBoost)?

I'm working on BRTs similar to this Mathworks example - http://in.mathworks.com/solutions/machine-learning/examples.html?file=/products/demos/machine-learning/boosted_regression/boosted_regression.html

It shows how to plot relative predictor importance, but not a way to generate partial dependence plots(PDP) that depict the relationships between the response and one predictor variable while controlling for the average effects of all other predictors.
