Thread Subject: displaying values

i have this code to find all the centroids which objects have the specific area. however, I couldnt find a way to display the values and maybe pass the values to a variable(s). I really appreciate it if somebody could help me with some demos.

below is part of the code:

id = find([s.Area] > 1000 & [s.Area] < 100000 );

    for ii = 1:length(id);
    hold on, plot(s(id(ii)).Centroid(1),s(id(ii)).Centroid(2),'wp','MarkerSize',10,'MarkerFaceColor','r'), hold off

i want to do something like.. %disp(['Center location is (',num2str(s(id(ii)).Centroid(1),4),', ',num2str(s(id(ii)).Centroid(2),4),')'])

thanks in advance!

doc fprintf:

fprintf('Center location is %f, %f \n',s(id(ii)).Centroid(1), s(id(ii)).Centroid(2));
