How to send data from matlab to arduino by Serial?

Hi guys, How can I send data from matlab to arduino? I'm trying to send 3 values to arduino using serial port, I used fprintf() but the value in arduino doesn't change as if it had never been sent it, because when I read the 3 variables in Matlab they have the same initial value, and the Read Led turns on.

It looks like you are using an older syntax. See this page:

You will want to connect using serialport and can write using write or writeline. See here:

I tried that syntax but it still doesn't work, so I tried to send the same data from Aruino IDE monitor serie and it works, so I don't why with Matlab, arduino doesn't get the data.

Perhaps if you could share some of the code you have tried.

Here are some examples you can test with:
