The function 'imfindcircles' should be the most promising path.

Please see the attached sample code by running the below command in the MATLAB R2018b command window to get the release specific documentation.

web(fullfile(docroot, 'images/ref/imfindcircles.html'))

Please note that you might need to play around with the parameter set in order to get a more accurate result. 

Also, the Circle Finder app on the File Exchagne is can be quite useful:
