最新的HHT时频分析程序By Huang and Wu

function freq = calcqf(quadrature, dt, smooth)
% calcf() - calculates the instantaneous frequency of the analytic signal
%
% syntax: freq = calcf(quadtrature, dt, smooth)
%
% where:
%   quadrature  - is the complex quadrature signal
%   dt          - is the time increment of the data
%   smooth      - median smooth
%   freq        - is the instantaneous frequency of the quadrature signal
