I would like to return the parallel circle-arc to a given circle-arc, displaced by a distance "e". I found packages that allow for example plot circle -arcs, like geom2d.rar. I'm looking for a similar package.
MATLAB: Does it exist an already developed module on matlab that returns a parallel circle-arc to another given circle-arc
parallel circle-arc

Come back with your code if you still can't figure it out.
Try this:
% Create sample data.
numCircles = 10;xy = rand(numCircles, 2);radii = 0.1 * rand(numCircles, 1) + 0.1;viscircles(xy, radii);% Label them so we know what circle is what.
for k = 1 : numCircles text(xy(k, 1), xy(k, 2), num2str(k));endaxis square;% See if any intersect
for k = 1 : numCircles % Compute the distance between centers.
distances = sqrt((xy(k, 1) - xy(:, 1)).^2 + (xy(k, 2) - xy(:, 2)) .^2); sumOfRadii = radii(k) + radii(:); intersectingIndexes = distances < sumOfRadii; % Don't compare circle to itself. Of course that one intersects!
intersectingIndexes(k) = false; % Convert to linear indexes
intersectingIndexes = find(intersectingIndexes); for k2 = 1 : length(intersectingIndexes) fprintf('Circle %d intersects with circle #%d.\n', k, intersectingIndexes(k2)); endend
You see
Circle 1 intersects with circle #2.
Circle 1 intersects with circle #5.
Circle 1 intersects with circle #7.
Circle 2 intersects with circle #1.
Circle 2 intersects with circle #5.
Circle 3 intersects with circle #7.
Circle 3 intersects with circle #9.
Circle 5 intersects with circle #1.
Circle 5 intersects with circle #2.
Circle 6 intersects with circle #10.
Circle 7 intersects with circle #1.
Circle 7 intersects with circle #3.
Circle 8 intersects with circle #9.
Circle 9 intersects with circle #3.
Circle 9 intersects with circle #8.
Circle 10 intersects with circle #6.
and it's trivial to find out if one circle is completely contained within another. See if you can do it.
