Hello Everybody,

I have two subclasses:

Line
Arc

Their objects will be creating a path by appending them on their end. These have their own "plotCurve" methods. I want to store these objects in an arrayi in order such like:

path = [line1,line2,arc1,line3,arc2,arc3,line4,arc4,arc5...];

(I think "path" should be the object of superclass "Path")

when I code something like;

for i=1:size(path)
    path(i).plotCurve;
    hold on
end

the result should be show. I should be able to see the whole path. (So, when the object of "Line" comes "plotCurve" method should be run and same for Arc objects).

Thanks in advance,
