<div dir="ltr">Hello,
<div><br>
</div>
<div>I want to calculate the covariance of the data I provide. In the function ft_timelockanalysis there is a portion where the covariance is being normalised over all trials by the total number of samples in all trials. </div>
<div><br>
</div>
<div><br>
</div>
<div>
<div>% normalize the covariance over all trials by the total number of samples in all trials</div>
<div>if strcmp(cfg.covariance, 'yes')</div>
<div> if strcmp(cfg.keeptrials,'yes')</div>
<div> for i=1:ntrial</div>
<div> if strcmp(cfg.removemean, 'yes')</div>
<div> covsig(i,:,:) = covsig(i,:,:) / (numcovsigsamples(i)-1);</div>
<div> else<br>
</div>
<div> covsig(i,:,:) = covsig(i,:,:) / numcovsigsamples(i);</div>
<div> end<br>
</div>
<div> end</div>
<div> else</div>
<div> if strcmp(cfg.removemean, 'yes')</div>
<div> covsig = squeeze(nansum(covsig, 1)) / (sum(numcovsigsamples)-ntrial);</div>
<div> else<br>
</div>
<div> covsig = squeeze(nansum(covsig, 1)) / sum(numcovsigsamples);</div>
<div><br>
</div>
<div> end</div>
<div> end</div>
<div>end</div>
</div>
<div><br>
</div>
<div>Please note that the cfg.removemean was selected as yes. </div>
<div><br>
</div>
<div>Can someone please explain what is the final data present in my covariance matrix? <br>
<br>
