MATLAB and Arduino: Ending Communication

Hello all,

This is the first project that I am working on with MATLAB or Arduino. I have experience with C++ and .spin language and I have figured out most of what I need for this particular task. It is very simple: Turn a turntable 45 degrees, take a picture. Do this 3 times and then close out of the program. I will figure out how to trigger the camera and receive pictures at a later date.

I was just wondering if there was any way to stop running the program once I have taken the pictures I need? I have looked at a lot of different places and they suggest just running an empty loop to "stop" the Arduino from doing anything. However, that will not work because I am interfacing that with my MATLAB GUI to where when the pictures are done, I need to return control to MATLAB.

I already posted this on the Arduino forum, but I figured coming here may help. I have already established communication between MATLAB and it operates my Arduino code below without a flaw once a button is pushed. The only problem is that MATLAB believes that their is a connection issue because the Arduino stops sending data back.

Is there a way to send something from Arduino once the pictures are done to end communication between the two? Thanks in advanced for your help.

clear ard;              %Resets ard
global ard;             %Creates a Global Variable for ard
ard = arduino('Com6');  %Opens Arduino on Com6, Change as Necessary

Why can't you just attach your m-file with the paperclip icon???
