waveletchangeinit.m

基于matlab的反演程序,用于地球物理勘探中射线追踪及偏移成像程序.

function waveletchangeinit(transfer,wavelet,tw,name,hfigmaster)

% waveletchangeinit(transfer,wavelet,tw,name,hfigmaster)
%
% WAVELETCHANGEINIT begins the WAVELETCHANGE dialog which allow the interactive
% alterations of a wavelet in any of the following ways:
%	tomin ... convert to its minimum phase equivalent
%	tozero ... convert to its zero phase equivalent
%	toall ... convert to its all pass equivalent
%	toinv ... invert the wavelet
%   tr ... time reverse the wavelet
%	window ... apply a temporal window
%	phsrot ... apply an arbitrary constant phase rotation
%	ghost ... include the effects of a near surface ghost
%
% The input parameters have the following meanings
% transfer ... a MATLAB string with a syntactically correct MATLAB command
%              which will transfer control to another program at the
%              conclusion of the dialog
% wavelet ... vector giving the wavelet amplitudes (time domain)
% tw ... vector giving the time coordinates of the wavelet amplitudes
% name ... name of the input wavelet
% hfigmaster ... handle of a master figure in control of this one.
