Matlab2025a、2025b的margin指令不更新裕度点
显示 更早的评论
采用Matlab2025（a版和b版）的margin指令绘出控制系统的Bode图后，若将横坐标由角频率（rad/s）切换为频率（Hz），相位裕度和幅值裕度点还停留在原处，不更新。

I treid to reproduce steps on R2025a.
Values in different units:
For rad/s
For Hz
On hovering over the blue dot, it shows Frequency values in different units and with different values.
Let me know if something differs in the above steps than your code.
Hope this helps!

No more code, just change the uints of the Bode Diagram from rad/s to Hz，Then the bug appeared
