matlab如何把regionprops里得到的数据转化为字符串后用text输出

Question

A=imread('700-2.bmp');
B=rgb2gray(A);
C=im2bw(B);
imshow(C);
E=bwlabel(C,8);
centers = regionprops(E,'Centroid','Area');

for k=1:length(centers)
if(centers(k).Area > mean([centers.Area])-std([areas.Area]))
x = centers(k).Centroid(1);
y = centers(k).Centroid(2);
text(x,y,string(centers(k).Area));
end
end

用string时显示不是字符串参数
