function [dataout]=mix(datain,weights) %function [dataout]=mix(datain,weights) % %lateral trace mixing with user specified weights %similar to INSIGHT module 'mix' % %datain - is in official DSI format %weights - is a vector of weight factors for the mix. ex. [0.12,0.76,0.12] %is a typical triangle weighted mix. elements of 'weight' should add up to 1 %length of weights or number of weights must be an odd number % %DSI customized VSP processing software %written by Kristen Beaty November, 1997 %$Id: mix.m,v 3.0 2000/06/13 19:20:50 gilles Exp $ %$Log: mix.m,v $ %Revision 3.0 2000/06/13 19:20:50 gilles %Release 3 % %Revision 2.0 1999/05/21 18:46:02 mah %Release 2 % %Revision 1.2 1999/05/17 17:15:02 mah %fixed help message % %Revision 1.1 1999/01/06 19:09:06 kay %Initial revision % % %Copyright (C) 1998 Seismology and Electromagnetic Section/ %Continental Geosciences Division/Geological Survey of Canada % %This library is free software; you can redistribute it and/or %modify it under the terms of the GNU Library General Public %License as published by the Free Software Foundation; either %version 2 of the License, or (at your option) any later version. % %This library is distributed in the hope that it will be useful, %but WITHOUT ANY WARRANTY; without even the implied warranty of %MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
