% TFE estimates transfer function between time-series objects. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % DESCRIPTION: TFE makes transfer function estimates of the time-series % in the input analysis objects. The estimate is done by taking % the ratio of the CPSD between the two inputs, Sxy, divided by % the PSD of the first input, Sxx: % Sxy / Sxx where x is the first input, y is the second input % % CALL: b = tfe(a1,a2,pl) % % INPUTS: a1 - input analysis object % a2 - input analysis object % pl - input parameter list % % OUTPUTS: b - output analysis object % % <a href="matlab:utils.helper.displayMethodInfo('ao', 'tfe')">Parameters Description</a> % % VERSION: $Id: tfe.m,v 1.36 2011/04/08 08:56:13 hewitson Exp $ % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% function varargout = tfe(varargin) % Check if this is a call for parameters if utils.helper.isinfocall(varargin{:}) varargout{1} = getInfo(varargin{3}); return end import utils.const.* utils.helper.msg(msg.PROC3, 'running %s/%s', mfilename('class'), mfilename); if nargout == 0 error('### tfe cannot be used as a modifier.
