I know that there are many posts on the subject of how to set the baud rate for serial connections in the MATLAB Support Package for Arduino but I have not seen a definitive solution.
It seems to default to 9600. There was some guidance posted here https://www.mathworks.com/matlabcentral/discussions/maker/29-baud-rate-of-arduino-hardware-support-package but the suggestions do not work for the latest release.
Would setting the baud rate in the operating system work?
Thank very much.

Hi Arthur,
The BaudRate can be specified while creating an arduino object. The BaudRate defaults to 115200.
For example,
>> a = arduino('COM5','Uno', 'BaudRate', 115200);
>> a.BaudRate
Refer to the documentation page of arduino to know more about the option at
