% this is a function to calculate instantaneous based on EMD method
%
%   function omega = ifndq(vimf, dt)
%
% INPUT:   
%          vimf:        an IMF;
%          dt:          time interval of the imputted data
% OUTPUT:
%          omega:       instantanesous frequency, which is 2*PI/T, where T
%                       is the period of an ascillation
