How do define BaudRate from MATLAB to Arduino?

I want to acquire data from Arduino and to plot it in MATLAB. I noticed that this process is very slow so, the sampling rate is just about a few tens [Hz]. Is there a way to increase the Baudrate of the Arduino board(Due), in the MATLAB script? IS there any other way to plot faster data from Arduino to MATLAB? e.g. about 1k [Hz]? I saw a few posts about it from the past but, yet cannot find a good answer.

Hi Ori,

Currently, there is no direct way to change the BaudRate with MATLAB SPPKG for Arduino. We will consider adding this feature in a future release. Until then, please refer to the post by Madhu in the thread at the link below, to be able to change the Baud Rate: https://ch.mathworks.com/matlabcentral/answers/259906-arduino-support-package-baud-rate

Thanks Arpita MATLAB Hardware Team - MathWorks

Hello! I'm using matlab 2021 version. Am I still not able to do this? I have the exact same problem. I'm able to get a real time plot of voltage that my arduino measures but only at a few tens [Hz], and I need it to be at 1000Hz. Can I do this using arduino or should I use other board like DAQ or Raspberry Pi?

Hi Teresa. Have your problem solved? I also have the same problem. no matter with matlab or simulink , there are only limited sample rate(less than 200 Hz) is available.
