non overlapping random circles
显示 更早的评论
in search of a code which can generate output like this on matlab . and the result is in polyshapes ,centre and radius
circles are randomly distributed at the periphery of square .
input is number of circels,max radius , minimum radius and area of circles

The FEX contribution metioned by Matt J produces cirlces that are closely packed. I wrote an alternative function that plots circles with random centers that do not overlap but do not have the requirement to be densely packed. That function can be downloaded here:
Here are some notes that pertain to your needs:
- One of the parameters you can set is whether the circles extend beyond the chosen border or not.
- At the top of the code, in the comment section, I give an example of how to calculate the area of the circles by using the function outputs.
Please feel free to play around with that function and its options. If you have any further question or problems, please follow up here.
Below are some examples produced by this funciton.
*A previous version of this solultion included the source code. I've since edited that code and uploaded it to the file exchange.

But is the pattern of circles generated in my solution or Adam's acceptable or not? That's the challenging part. Once we've given you code that generates a proper pattern of circles, it should be a trivial matter for you reformat the output as polyshapes yourself.

jahanzaib ahmad, I've edited my solution. Please see the link in my answer above and feel free to play around with the function that has been adapted to suit your needs.
Specifically, you can use the outputs of that function to add polyshapes and to calculate area. See the examples I've provided within the function file.

I cannot run your function. actually I ran it as the following code:
[Cen,Rad] = bubblebath()
and the error is:
Error in bubblebath (line 131)
radMat = xyr(:,3) + xyr(:,3)';
please help me in using your code
Regards

What's the full error message (copy-pasted)?

can we maintain periodicity here. cutout portion of boundary should fall on opposite side

Yes, starting in bubblebath() vs 2.3.0 you can set edgeType=3 to wrap circles that expand beyond the frame edge.
Example:
rng('default') % for reproducibility
S = struct();
S.frameSize = [30 30];
S.circSize = 4;
S.nSizes = NaN;
S.edgeType = 3; % <-- flag to wrap edges
S.supressWarning = true;
bubblebath(S)

its not a packing problem are cirlces are not fully inside box ,

The circles aren't fully inside of the frame in the example you provided either.
