Find the distance between the longest endpoints of a skeleton

How to find the distance between the longest endpoints of a skeleton?

    LengthBr = bwmorph(finalBinaryImage,'skel',Inf);
    endImg    = bwmorph(LengthBr, 'endpoints');
     figure;imshow(LengthBr );

      hold on; plot(endPts(:,2),endPts(:,1),'*');
       hold off;

Thanks. This is part of another code which I needed to get to work. There are multiple object detected and turned into skeleton. I then want to get the length of each. Cheers
