[Eeglablist] Epochs - How to average epochs for power extraction

Thank you for any responses to the following question.
I am hoping to use Makoto's code for extracting alpha power (found on wikipedia):
[spectra,freqs] = spectopo(EEG.data(2,:,:), 0, EEG.srate); %channel 2
alphaIdx = find(freqs>8 & freqs<13);
alphaPower = mean(10.^(spectra(alphaIdx)/10));
I have currently selected my event of interest (condition 3, for example), which contains several epochs.
Can I assume that the alphaPower calculated will be from an average over the currently selected epochs?
I am currently analyzing a single subject.
