I try to run the example "ev3_communication"(LEGO MINDSTORMS EV3 Programming Using Simulink) for Lego Mindstorms EV3 using Simulink Matlab R2014b. I already download the Simulink Support Package for LEGO MINDSTORMS EV3 Hardware.
When I type:
b = Brick('ioType', 'usb')
I get the following error:
Undefined function 'Brick' for input arguments of type 'char'.
Can you guys help me out to understand what I am missing here ? I would appreciate is somebody can walk me through. Any idea is welcome or if you have a link or tutorial. I would appreciate that very much

I was having the same trouble with my arduino, I re-installed from withing matlab using the addon button and was then able to create the objective (b=brick(...)). So try this if you have not already
addons
get hardware support package
install from internet
lego mindstorm ev3
next
Hopefully that will workout for you if not let us know what it says.
