Function Synopsis

y = detrend(x,o)

Help text

DETREND Remove a linear trend from a vector, usually for FFT processing.
	Y = DETREND(X) removes the best straight-line fit from the data in
	vector X and returns it in vector Y.  If X is a matrix, DETREND
	removes the trend from each column of the matrix.
	Y = DETREND(X,0) removes just the mean value from vector X, or
	the mean value from each column, if X is a matrix.
