Damped function second low

Hi, how can I find a second low of a damped function in Matlab?

Do i have to use fzero?

I have no idea what ‘second low’ means or refers to, or what you are doing.

If you want the minima of the damped waveform, use the islocalmin on the waveform, or use findpeaks on the negative of the waveform.
