When a signal Sub-banded using [C,L] = wavedec(S,8,waveletFunction), How should I Calculate Energy of bands like Alpha Or Beta??? I mean's that I must use D7 = wrcoef('d',C,L,waveletFunction,7) for Alpha and calculate Energy of D7 Or I must use cD7 = detcoef(C,L,7) and then calculate Energy of cD7?? which one is correct??
please help me

The energy should be calculated on the wavelet coefficients not a reconstruction (projection) as obtained with wrcoef. For this application, consider MODWT or MODWPT.
