When used for vibration signals, it always displays that the extraction of the STFT exceeds the array boundary. Is there any comment on this?

Dear Chao He,

would you kindly specify at which step of the algorithm is the issue detected?

My first guess is that there is a problem with the ridge extraction algorithm (ridge_ext). Please, check that the extracted ridge is within the boundaries of the time-frequency plane specified when computing the STFT.

Cheers
