Get an Error connecting LEGO Mindstorms EV3 via bluetooth with MATLAB but can connect with Simulink; How do I fix this?

The Matlab syntax is

myev3 = legoev3('bluetooth','COM6');

The error generated by the compiler is

Error using legoev3 (line 199)

Failed to connect to EV3 through Bluetooth. Please check your Bluetooth connection.

I have checked the properties of the bluetooth; serial connection is OK.
