boundaries = bwboundaries(pad);
thisBoundary = boundaries{1};
% Get the distances of the boundary pixels from the centroid.
distances = sqrt((thisBoundary(:,1) - a2).^2 + (thisBoundary(:,2) - b2).^2);
% Scan the boundary to find the pixel on it that is
% farthest from the centroid.
maxRadius = max(distances);
a2,b2 are centroid coordinates of the object named 'pad'
above code calculate the farthest distance. could anyone please tell what will be the coordinates of that point on the object boundary.

Air code:
[maxRadius, maxRadiusIndex] = max(distances)
maxPointCoord = thisBoundary(maxRadiusIndex,:)
Look at the doc for the second output of max
