Hi, I use rectangle function to draw a rectangle with two ends curved using following codes:
Rec = rectangle('Position',[1,1,10,5],'Curvature',1);
Will it be possible to get the (x,y) coordinate matrix of Rec?? Thanks for the help.

What is "the (x,y) coordinate matrix" of Rec ?
You can get() the Position property of Rec to retrieve the [1,1,10,5]

Hi Walter, This did not provide the feature of the curved part though. I think I address my question more precisely as how to get the xy of a "curved rectangle"

Sorry, I did not notice about that.
I do not know of any method to extract the coordinates. There might be one that is not obvious, but I cannot test that at this time.

Ran in:
To get the coordinates, just follow the index of the array:
r = rectangle('Position',[20 -3 10 10]);
r.Position(1) % x value
ans = 20
r.Position(2) % y value
ans = -3
