Extract patches and save its coordinate points

I have an image [800 x 900 x 4 ]. I want to extract patches [patch size= 17 x 17] and at the same time save its corresponding coordinate (center).Can anyone give me suggestions or code for that?.
Thanks

You previous question suggests you already have the center coordinates, why not save that variable as well? Anyway, you can easily extend the solution there to include the center coordinate.
(Also, it's better not to overwrite the patch function with a variable)
selected_patches = cell(length(x),2);
for i=1:length(x)
xtemp=x(i)+[-8 8];
xtemp(xtemp<1)=1;xtemp(xtemp>size(IM,1))=size(IM,1);
ytemp=y(i)+[-8 8];
ytemp(ytemp<1)=1;ytemp(ytemp>size(IM,2))=size(IM,2);
selected_patches{i,1}=IM(xtemp,ytemp,:);
selected_patches{i,2}=[x(i) y(i)];
end
