circumference of a circle covered by other intersecting cirlces

I have a circles with given same radius and their center coordinates. How can I find out whether the circumference of a circle is covered by other intersecting circles in that plane

This hasn't got much to do with matlab.

Two circles will intersect iff the distance between their centre is less than the sum of their radii.

Dear Sir, I just want to see whether the circumference of a circle is completely covered by other cirlces in the plance or not.

Intersection can be easily found by circcirc function

Thanks in advance
