Function 'subsindex' is not defined for values of class 'serial'.

I'm working on getting a serial connection between arduino and Matlab. The error reads:

Function 'subsindex' is not defined for values of class 'serial';
Error in lights_controlled (line 36)
set(arduinoCom, 'DataBits', 8);

The segment of code reads:

    global arduinoCom now bb f go flag_saving connected quitgui collecting  ...
    deletedfile enable_results reset C sensor_avg_upright saveduration ...
    h_timerinput h_startbutton h_timerbutton flag_stop flag_timed...
    flag_start starttoggle Upper_time h_resultsbutton;
arduinoCom = serial('COM5');
arduinoCom.BaudRate=9600;
%arduinoCom.ReadAsyncMode = 'continuous';
set(arduinoCom, 'terminator', 'LF');
set(arduinoCom, 'DataBits', 8);
set(arduinoCom, 'StopBits', 1);
set(arduinoCom, 'Parity', 'none');
set(arduinoCom, 'Timeout', 60);

Do you have any suggestions for fixing this? The code was working and we hadn't made any changes but now it is not.

Best, Perri

You've defined a variable named set in the workspace and MATLAB interprets your call as an attempt to index into that variable using the serial object. Delete the variable.
