matlab interface

Hi,
I am trying to control CineMoco with MATLAB. I cannot find any open-source reference so I start to do it by myself.
link for CineMoco http://cinetics.com/controller/
Now based on 404 - PAGE NOT FOUND,
I can control the motor by serial monitor of Arduino, but when I open serial port in MATLAB, there is no connection. There are two possible reasons,
First Arduino have some communication protocol with CineMoco, since CineMoco install a engine from GitHub - cinetics/CineMoco: Update to v-2.5 in miniE_cineMoco/mE_CM_dragonframe.ino.
Second, I maybe did wrong in MATLAB to open serial.

Now I trying to solve the problem. The solution I get is to setup a communication between MATLAB and serial monitor of Arduino. I want to ask if there is any reference to do so?
Thank you

The solution I get is to setup a communication between MATLAB and serial monitor of Arduino.

No, that is not the solution. The Serial Monitor application that runs on the PC is a pretty dumb application. All it knows how to do it send data to the Arduino, via the serial port, and show data that the Arduino sends to the serial port. It has no idea how to interact with MatLab.
