<DIV> </DIV>
<DIV>I have a problem about the script of ICA. I got two matrices:
FW and mixedsig with other method. FW is the seperating
matrix, equal to EEG.icaweights in EEGlab. mixedsig is the original
EEGdata. Now, i want to get the following variable using FW and mixedsig and
return them to EEGlab: EEG.icaact, EEG.icawinv, EEG.icasphere, EEG.icaweights.
My script is as follows:</DIV>
<DIV> </DIV>
<DIV>
<DIV>EEG.icaweights=FW;</DIV>
<DIV>EEG.icasphere=eye(size(EEG.icaweights,2));</DIV>
<DIV>EEG.icaweights=EEG.icaweights*EEG.icasphere;</DIV>
<DIV>EEG.icawinv=pinv(EEG.icaweights*EEG.icasphere);</DIV>
<DIV>EEG.icaact=EEG.icaweights*mixedsig;</DIV></DIV>
<DIV><FONT size=2 face=Verdana></FONT> </DIV>
<DIV>I am not sure it is correct. could you help me check it? </DIV>
<DIV> </DIV>
<DIV>Thank you very much!</DIV>
<DIV> </DIV>
<DIV>Best,</DIV>
