How can use a MATLAB value in Arduino Uno code?

Dear all,
I have a question regarding to sending information between MATLAb and an Arduino Uno. I have made a little Matlab program that detects red objects from a webcam, and labels their coordinates. Now i have a setup with an Arduino Uno that includes a servo. I want this servo to respond to the variable y-coordinate send from my matlab program. How do i do this?
my detection program is:
if true
cam = webcam;
thresh = 0.29;
nFrame = 0;
while(nFrame < 100)
imgRGB = snapshot(cam);
imgGrey = imsubtract(imgRGB(:,:,1), rgb2gray(imgRGB));
imgGrey = medfilt2(imgGrey, [3 3]);
imgGrey = im2bw(imgGrey, thresh);
imgGrey = bwareaopen(imgGrey,200);
bw = bwlabel(imgGrey, 8);
stats = regionprops(bw, 'BoundingBox', 'Centroid');
imshow(imgRGB)
hold on
for object = 1:length(stats)
bb = stats(object).BoundingBox;
bc = stats(object).Centroid;
rectangle('Position',bb,'EdgeColor','blue','LineWidth',1)
plot(bc(1),bc(2), '-m+')
a=text(bc(1)+15,bc(2), strcat('X: ', num2str(round(bc(1))), ' Y: ', num2str(round(bc(2)))));
set(a, 'FontName', 'Arial', 'FontSize', 12, 'Color', 'blue');
end
hold off
nFrame = nFrame+1;
end
the value bw(2) is the y-coordinate that i want to use to move my servo. what is the corresponding code that i should use in arduino? and matlab?
regards,
Kasper NL

Hi Kasper van Wijk,
Once you have the MATLAB Arduino support package installed, go through this example which shows how to use the MATLAB Support Package to control a servo motor. Once you go through the example you will be able to modify it suit your algorithm of making the servo respond to 'bw(2)'.
Thanks, Abhishek

Hello! I have built a robotic arm with 3 servo and a camera mounted on the upper arms. Looking a code to detect red objects via the camera and move the arm at them. I suppose that something similar u have built ....? If you can help I would appreciate it !!! Thanks

Hello! I'm from Brazil. I need your code to apply in a neurosurgery softwrae. Please, if you can, please send this red color code to my email. E-mail: <mailto:rkhayker@gmail.com rkhayker@gmail.com> I'm grateful already!
