idamnjanovic@70 2 %ADD_DC Add DC channel to signals.
idamnjanovic@70 3 % X = ADD_DC(Y,DC) adds the specified DC value to the (possibly
idamnjanovic@70 4 % multi-dimensional) signal Y, returning the result as X. DC should be a
idamnjanovic@70 5 % scalar value.
idamnjanovic@70 6 %
idamnjanovic@70 7 % X = ADD_DC(Y,DC,'columns') where Y is a 2D matrix and DC is an array of
idamnjanovic@70 8 % length size(Y,2), treats the columns of Y as individual 1D signals,
idamnjanovic@70 9 % adding to each one the corresponding DC value from the DC array. X is
idamnjanovic@70 10 % the same size as Y and contains the resulting signals.
