Crossover frequency

Hello, (sorry I'm french..)

I have a transfert fonction, for example Gs=5/(s²+s+1).

I can found "gain margin" and "phase margin" with functions:

g_margin and p_margin .

But how can I find the Crossover Frequency corresponding ?

With the Bode diagramm, the crossover frequency is near (close) to : w0=2,33 rad/s

Does it exist a direct function?

Thank you for your aswer.

The same function will give you the crossover frequency. You just have to use a 1X2 row vector on left hand side as given below:
Where h is the Transfer function
