关于annotation object的旋转

今天一同学在Matlab群里问如何将annotation object进行旋转，虽然我在写论文很忙，但是这种牛角尖的问题我就喜欢去钻研，于是google，baidu都用上，结果都没找到合理的答案，最后还是在matlab的doc文档里面找到了答案，下面贴出代码

ax = axes('XLim',[-2 1],'YLim',[-2 1],'ZLim',[-1 1]);t1 = hgtransform('parent',ax);view(3)h = annotation('rectangle',[0.3 0.3 0.5 0.5],'FaceColor',[1 1 0]);set(h,'Parent',t1)for r = 1:.1:10*pi    % Form z-axis rotation matrix     Rz = makehgtform('zrotate',r);     % Set transforms for both groups    set(t1,'Matrix',Rz)    pause(0.1);    drawnowend
