- You will first program your Arduino board, with the given code, using Arduino IDE. Download the Arduino code, open the Arduino IDE and create a new file and paste the downloaded code in the new file. Upload the program to the Arduino board.
- Note the port number for Arduino board from the Arduino IDE. Go to Tools menu > Port and note the port number such as COMx.
- After uploading the code, keep the Arduino connected using USB cable and open MATLAB.
- In the MATLAB code change the line
How to use Arduino code written in Arduino IDE file in MATLAB? How does it work?

Greetings. I came across with this project:
In the link, two files were provided: one for matlab, one for arduino. The programmers used the centroid extracted from the face detected and tracked in matlab, and sent the coordinates to arduino to control the servos.
My question is: 1. How does the fopen(arduino) work? How does matlab know which arduino code file to access?

MATLAB does not need to know which Arduino sketch file you are using. Here is the procedure of what you need to do.
and change COM6 to COMx you noted from MATLAB.
Now when you run the MATLAB code, it will communicate with the Arduino.

I don't think is possible to write hybrid code, you have two solution in my opinion:
1) write everything in matlab: performances arent great, but you can comunicate with the board very easily and in real time.
2) write everything in arduino and comunicate to the board through the COM port as shown by Ameer: it's faster, but less easy to do.
