How can I rotate a curved rectangle?
显示 更早的评论
I have created a curved rectangle and now I want to rotate it. I know I can not rotate using rectangle commande. I also tried to plot the rotated rectangle using "fill" but then I can not add curvature.
So, the question is, How can I plot a rotated curved rectangle?

rectangle2() from the file exchange can rotate a curved rectangle.
rectangle2([x,y,w,h],'Curvature',[a,b],'Rotation',deg);

HI,
so you have a set of points (x,y) describing a curved rectangle. I guess the keyword here is rotation matrix:
Create the Matrix accoringly and multiple it with your (x,y) values to get the rotated rectangle.

Yes in that case no chance. You would need do draw that rectangle by yourself to get x,y points and then rotate it by your own or using the rotate function.

The rotate function can rotate graphic objects:
But not a rectangle object :(

You need to create your own version of the rectangle function which calculates the curved rectangle from scratch. Afterwards you can plot it an rotate it.

If it's ony about plotting try to call this after your plot function:
alpha = 30; set(gca, 'View', [alpha 90]);
