Question

below I am creating a bode plot of the specified transfer function. I want to know if there is an option using bode plot options to mark the corner frequency on the plot and determine the magnitude and phase at that frequency. How would I go about doing this on the plot? NOTE: BELOW IS THE CODE FOR MY BODE PLOT OF THE TRANSFER FUNCTION.

num=[1]; %set the numerator in a matrix
den=[1 1.5]; %set the denominator in a matrix
Transfer_Function=tf(num,den) % use the tf function to set the transfer function
h=bodeplot(Transfer_Function) %create a bode plot
grid
setoptions(h,'FreqUnits','Hz'); % set my units to hertz along the x axis instead of rad/sec

Explanation / Answer

you can use margin command to mark phase cross over frequency and gain cross over frequency.other cutoff frequencies can be visually identified and marked using edit figure properties option in figue.

most problably one is interested in   phase cross over frequency and gain cross over frequency for that syntax is

''margin(h)''
