DETREND - detrend an HFRC object Usage: hfrc_obj2 = detrend( hfrc_obj, ... ) This function removes the trend from the components of the total currents contained in the HFRC object. Each column of U and V (ie. each time series) has its trend removed. ... represent extra arguments passed to the detrend function. See the help for the normal detrend function for more information. You probably want to pass this function at least 'constant' so that it just removes a mean. NOTE that this function is best for data with no holes - i.e. interpolated data, like one would have before performing a fft or EOF. For more robust detrending with missing data, see polyfit. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% $Id: detrend.m,v 1.3 2002-12-20 21:21:46 dmk Exp $ Copyright (C) 2001 David M.
