MATLAB calls wrong "encode"-function

I want to call the encode-function from Computer Vision Toolbox in the file bagOfFeatures.m, but MATLAB always calls the wrong encode-function from Communications Toolbox:

>> which -all encode
/Applications/MATLAB_R2020a.app/toolbox/comm/comm/encode.m
encode is a Java method                                                % org.apache.commons.codec.binary.Base64 method
encode is a Java method                                                % org.apache.commons.codec.BinaryEncoder method
encode is a Java method                                                % org.apache.commons.codec.Encoder method
encode is a Java method                                                % java.net.URLEncoder method
/Applications/MATLAB_R2020a.app/toolbox/vision/vision/bagOfFeatures.m  % bagOfFeatures method

If I call the bagOfFeatures-function prior to the encode-function it works, but I created my bag once, saved it as a .mat-file and now load it without calling bagOfFeatures.

How can I tell MATLAB explicitly which encode-function I want to call?

Nevermind, I just realised that the bag was loaded as a struct.

When I correctly load it as a bagOfFeatures-object, MATLAB finds the correct function.
