You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: Command.m
    path of file: ./repos/Robotics-Toolbox/rvctools/release10.3.1/robot/interfaces/EV3
    
    the code of the file until where you have to start completion: % EV3 command constructio
    
function displayHex(cmd)
            % Command.displayHex Display the command message (hex)
            %
            % Command.displayHex() prints the command message to the MATLAB
            % command window in hexadecimal format.
            %
            % Example::
            %           cmd.displayHex()
            
            loose = strcmp( get(0, 'FormatSpacing'), 'loose');
            if loose
                disp(' ');
            end
