Hello octaveforge developers
I have found a bug in pwelch.m for the case when a cross power spectrum is
calculated and 'none' is passed as a parameter in order to remove mean from
both x and y inputs:
line 718:
elseif ( rm_mean ~= 2 ) % remove linear trend from segment
should be chamged to:
elseif ( rm_mean == 2 ) % remove linear trend from segment
Treatment of y should be equivalent to the treatment of x (line 707).
The above change produce results which are compatible with matlab.
Regards
Nitzan Arazi
