Let's say that I have a vector holding a bunch of shapes:
x =
1×3 graphics array:
Ellipse Rectangle Circle
These shapes have just been loaded to the workspace from a .mat file. Because of this, they are not drawn on any axis.
How can I draw these images with code on a parent axis?

Joseph - you could perhaps try changing the parent property of the stored graphics object to be that of the new parent axis. For example, we can create a recrtangle object on one figure
>> figure
>> axis([0 10 0 10])
>> hRect = rectangle('Position',[1 2 5 6]);
and then "transfer" this rectangle to another figure
>> figure
>> axis([0 10 0 10])
>> set(hRect, 'Parent', gca);
Perhaps this will work for you too.
