Help using rectangle() function to generate a matrix for image processing

Hi y’all i have a question about the function rectangle(), im using it to make 6x4 disk grid.

I was trying to use viscircles() as it would be much easier, but i cant fill them in appropiately.

Im using it to generate circles, but for the life of me I can not figure out how to save the figure output.

My code currently reads:

for i=1:24
h=rectangle('Position', [px(i) py(i) d d],'Curvature',[1,1],'FaceColor',[0 0 (1/24)*i]);
end

Where px and py are the specific positions where i want the disks printed, and d is the diameter of those disks.

These were read from imfindcircles(), giving me specific points that each circle is from.

Each one needs to be a different value (preferably 1:24). a circle of 1’s then 2’s and so on an so forth.

this is what im getting, which is exaclty what i need. But i have no way of saving it as data.

I have an idea to try the insertshape() command, but it seems like i couldnt save it as a [0 255] value instead of a color.

If you have any ideas or suggestions please reach out.

To save the figure generated by the code provided by you, you can use the savefig function as follows:

savefig();

If you wish to save the data (attributes of each rectangle) of the figure, you can create a structure and log the data into it with every iteration.

%dummy arrays 
px=[1,1,1,2,2,2]; 
py=[1,2,3,1,2,3]; 
d=1; 

rect_data = struct; 
for i=1:6
