please create matlab code :- system identification, modal analysis, and estimation of vibration frequencies and damping ratios.
Normalized amplitudes of complex frequency response function of the bridge estimated from Welch’s average power spectral density function due to vehicular movement-based excitation. The gray lines correspond to 10 segments of the measurements and the black lines show their average.Normalized amplitudes of complex frequency response function of the bridge estimated from Welch’s average power spectral density function due to vehicular movement-based excitation.
