Problems when connecting to my Arduino UNO R3

I have Matlab R2016a, I have installed MATLAB Support Package for Arduino Hardware version 16.1.1 I got this message when trying to connect to my Arduino UNO R3:

>> a=arduino

Updating server code on board Uno (COM4). Please wait.

Undefined variable "ide" or class "ide.internal.getArduinoIDERootDir".

Thanks a lot for advise or indicate a hint to solve
