In reply to Gehan Abouelseoud. I believe that you are referring to James Tursa's submission - you can get it here: https://www.mathworks.com/matlabcentral/fileexchange/30672-mxgetpropertyptr. Inside the submission, use the files mexPropertyPtrSDC.c, mexPropertyPtrSDC.h. The submission contains various Matlab and C test files that can help understand how to use the code, as well as a PDF document explaining the technical details. Note that the submission files have not been updated since 2019 and may possibly fail on recent Matlab releases; they rely on deeply undocumented aspects, which may easily break across Matlab releases.

Just an small additional comment on "Reading private properties". If for whatever reason you do not want s = struct(obj) to reveal the structure, you can define inside the methods block the method "struct"

methods
    function s = struct(obj)
        % ... do nothing...., or show error or...
    end
end

Then s = struct(obj) will show nothing (or an error, or...) . But there is a solution for this too: s = builtin('struct',obj). Best regards
