I have the following code in a GUI which saves a set of user-drawn lines to an array.
h = drawline(handles.axes1,'Tag','userLine');
However, when I save this to a .mat file like so:
lineHandles = findobj(handles.axes1,'Tag','userLine');
save('roi.mat','lineHandles')
I get a 0x0 GraphicsPlaceholder object when I load it back.
So, how do I go about saving the actual Line objects and not the handle?
Thanks in advance.

Answered my own question: created deep copy
lines = lineHandles(:,:);
save('roi.mat', 'lines');
