I am doing OMA of a footbridge and I have a 2 records in each set up. I am no that much used to MATLAB commands, but I can understand it easily now, as I started to look at it deeply. I would like to draw singular values, find frequency, mode shapes and damping ratio and if possible MAC value at each modal frequency. I have read IVAN help on some FDD question, it looks helpful, but I have may doubts on it, if anyone one can clarify it for me, I would appreciate.

Thanks.
