I need to save the output [xi ,yi, P] in a 9x3 matrix
this is the code i currently have
for v = 1:9
CN = centroids(v,:); %Which Row
x = CN(1);
y = CN(2);
[xiv,yiv,P] = impixel(rgbG,x,y); %rgbG is the image that i am getting pixel color from
end
This is is i want the output to look like
[xi1,yi1,P1]
[xi2,yi2,P2]
[xi3,yi3,P3].......
So on so forth
thank you!

Here is a simple adaptation of your code:
M = zeros(9,3);
for v = 1:9
CN = centroids(v,:); %Which Row
x = CN(1);
y = CN(2);
[xiv,yiv,P] = impixel(rgbG,x,y); %rgbG is the image that i am getting pixel color from
M(v,:) = [xiv, yiv, P];
end

Thank you for your quick response, I get a error, "unable to preform assignmanet because the size of the left side is 1-by-3 and the size of the right side is 1-by-5"

If that output is 1x5, then it cannot be stored in a row of a 9x3 matrix. You could instead define M as a 9x5 matrix, or use a cell array.
