How can I send a pwm signal towards a motor with arduino in matlab

Hello,

How do I send a PWM signal towards my motor, so that I can control it's speed?

I tried to use analogwrite, because on arduino IDE I can use it to control the motor. But on Matlab I can't use analogWrite, because the command doesn't exist.

I tried to use writePWMDutyCycle, but I couldn't control the motor with it.

Could someone plz help me!

I have the following code (this is just one button for the gui and the other buttons have the same code:

% --- Executes on button press in Snelheid100_button.
function Snelheid100_button_Callback(hObject, eventdata, handles)
% hObject    handle to Snelheid100_button (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA
a= arduino();
analogWrite(3,80);
clear a;

Can you use 'writePWMVoltage' command?

Documentation is below.

I tried that but that isn't my thing and then I need to figure out which voltage output is die exact PWMsignal. So I prefer it to be with writePWMDutycycle
