What is the mean of "@"

Hello everybody: when I use the LTI of the MATLAB, I am sure that I was trouble to understand the meaning of "gain margin: 10.4@482". I'm look forward to the reply from those who have power in the field. Thanks! Jihao Liu

It is still not clear to me, what you are exactly doing and which command creates the string you are asking for. I expect that such question are solved in the documentation of the used program. Did you read it already?

@Daniel: I do not see a @ there - but I admit I cannot recognize anything on the picture at all. Funny.
