% X input signal to be ploted.
% Mode can take one of the following values:
%       1:  for real valued functions,
%       2:  for ploting real and imaginary parts of complex valued vectors,
%       3:  for ploting real and imaginary parts and also absolute value of complex valued vectors,
%       default value of mode is 1 for real vectors and 2 for comlex vectors.
