Hi.,i ve to find the centroid of the wavelet coefficients on each frame of the audio signal. i've applied wavedec to decompose the signal into 5 level.,from that i obtained ca5,ca1,ca2,ca3,ca4,ca5.I have to calculate the energy and centroid of the wavelet coefficients on each frame.,How can i do it?Is there anyone know about this?
