setting OOBPredictorImportance to 'on' or true generates error

I'm trying to use a random forest as a feature ranking tool, and the documentation for TreeBagger says that I should be able to turn on the OOBPredictorImportance by specifying it as a property, such as B = TreeBagger(50,training_set,training_labels,'FBoot',0.667, 'OOBPredictorImportance', 'on') but when I do I get the error: Invalid parameter name: OOBPredictorImportance. Am I missing something about specifying properties?

You are likely using an older release of MATLAB. Refer to the doc for that release or type 'help TreeBagger.TreeBagger' to see parameter names. The old name for that parameter was 'oobpred'.

I'm also getting this error, although I'm running 2017a and version 11.1 of the Statistics and Machine Learning Toolbox.
Rather confused!
(for what it's worth, the older argument 'oobpred' didn't work either)

Turns out my problem was arising due to trying to pass tall arrays into TreeBagger, which creates a CompactTreeBagger class which does not support the OOb prectiction/error methods.
