Sending data larger than 1 byte from Arduino to Simulink via Serial Communication

I want to send simply numbers from Arduino to MATLAB via serial communication. I am perfectly sending values in between 0-255 however I also want to send larger values. Probably, Simulink reads it byte by byte however I couldn't figure how to combine those bytes to get a meaningful data.

Below, you may see my Arduino code and simulink block diagram.

My question can be simplified as this; "How can I send the double value 500 to MATLAB Simulink from Arduino?" I want to take that number 500 as a number to use control applications for example.

Thanks.
