MATLAB: Error connecting Arduino hardware to MATLAB R2018b

arduinoMATLAB

I installed MATLAb support package for ardunio hardware. When I type a=arduino() in the workspace. I get the error message 
>> a= arduino ()
Updating server code on board Mega2560 (/dev/cu.usbmodem14101). This may take a few minutes.
Undefined variable "ide" or class "ide.internal.getArduinoIDE
I'm using Mac by the way. Does anyone know what may be the problem?

This issue can be resolved by doing a clean re-installation, rather than a regular re-installation, of the "MATLAB Support Package for Arduino Hardware".
Please see the below resource for the steps to do a clean re-installation of a support package:
