function x = add_dc(y,dc,columns) %ADD_DC Add DC channel to signals. % X = ADD_DC(Y,DC) adds the specified DC value to the (possibly % multi-dimensional) signal Y, returning the result as X. DC should be a % scalar value. % % X = ADD_DC(Y,DC,'columns') where Y is a 2D matrix and DC is an array of % length size(Y,2), treats the columns of Y as individual 1D signals, % adding to each one the corresponding DC value from the DC array. X is % the same size as Y and contains the resulting signals. % % See also REMOVE_DC. % Ron Rubinstein % Computer Science Department % Technion, Haifa 32000 Israel % ronrubin@cs % % April 2009 if (nargin==3 && strcmpi(columns,'columns')), columns = 1; else columns = 0; end if (columns) x = addtocols(y,dc); else x = y + dc; end
