% SUMJOIN sums time-series signals togther %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % DESCRIPTION: SUMJOIN sums time-series signals togther. The start time of % each signal is taken in to account when summing. The signals % are zero-padded at non-overlapping times. % % s1: |. . + + | 0 0 0 0 0 % s2: 0 0 | + + + + | 0 0 % s3: 0 0 0 | + + + + . | % % CALL: b = sumjoin(a1, a2, pl) % % EXAMPLES: % % a1 = ao(plist('tsfcn', 'randn(size(t))', 'fs', 10, 'nsecs', 10, ... % 't0', 10000)) % a2 = ao(plist('tsfcn', 't', 'fs', 10, 'nsecs', 15, 't0', 15000)) % b = sumjoin(a1,a2); % iplot(a1,a2,b); % % <a href="matlab:utils.helper.displayMethodInfo('ao', 'sumjoin')">Parameters Description</a> % % VERSION: $Id: sumjoin.m,v 1.19 2011/04/08 08:56:12 hewitson Exp $ % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% function varargout = sumjoin(varargin) % Check if this is a call for parameters if utils.helper.isinfocall(varargin{:}) varargout{1} = getInfo(varargin{3}); return end % if nargout == 0 % error('### join cannot be used as a modifier.
