MATLAB R2018B documents the commands oobPermutedPredictorImportance and predictorImportance but these commands are not recognized by MATLAB. This is true for both the command line and when running m-code.
I have developed an tree ensemble model and I need to determine the predictor variables importances.

It is a method of that class, not a plain old function. It will only work when its first input is one of those objects. You can't, for example, say oobPermutedPredictorImportance(magic(4)) because magic(4) returns a double array, not a RegressionBaggedEnsemble object.
The same general answer holds for predictorImportance, though it may be a different class or a different set of classes that define this method.
