Matlab interfacing with arduino ERROR I installed the MATLAB support package for arduino in my MATLAB r2013a today.
Now I plugged on my Arduino in my usb port.

And ran the command:


  
    a = arduino()
    
    Error: Undefined function or variable 'arduino'.
  


When I get:


  
    a = arduino('COM18')
    
    Undefined function 'arduino' for input arguments of type 'char'.
  


I have checked that this package has been installed.


It is grey.


Any help will be appreciated.

Thanks very much

Anupam.
Arduino support within MATLAB came with Matlab-2014a onwards, you are using R2013a

Arduino support within SIMULINK came with Matlab-2012a onwards

for your release you can only interact via a simulink model
