Unrecognized method, property, or field 'OOBError' for class 'TreeBagger'.

Error in RF_Classification (line 39)

Undefined function 'mean_squared_error' for input arguments of type 'table'.

Any help to fix above errors would be highly appreciated.

oob_error = rf_classifier.oobError;

There is no property or method named OOBError for TreeBagger objects; there is a method oobError() for TreeBagger objects.
