FT_PREPROC_DETREND
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_preproc_detrend”.
FT_PREPROC_DETREND removes mean and linear trend from the data using using a General Linear Modeling approach. Use as [dat] = ft_preproc_detrend(dat, begin, end) where dat = data matrix (Nchans X Ntime) begsample = index of the begin sample for the trend estimate endsample = index of the end sample for the trend estimate If no begin and end sample are specified for the trend estimate, it will be estimated on the complete data.
