eqndefinit.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 eqndefinit(transfer,hmasterfig,lognames,logdefaults,coefs,...
		exps,newlogdes)

% eqndefinit(transfer,hmasterfig,lognames,logdefaults,coefs,...
%		exps,newlogdes)
%
% EQNDEFINIT is called by LOGEDIT to initiate a dialog  to define the
% computation of a new log from existing ones via an algebraic equation.
% The equation is of the form ((a*l1^k + b*l2^m)/(c*l3^n+d*l4^o))^p 
% Here l1,l2,l3,l4 are logs and the other terms are scalar constants. The
% dialog allows the definition of the logs, the scalars, and the destination of
% of the computed log.
%
% transfer ... transfer command to be called when the user terminates
%		the dialog
% hmasterfig ... handle of the masterfigure (usually a LOGEDIT window) in
%		control of the dialog
% lognames ... list of names of logs with individual names separated by '|' 
%		such as: 'fred|sam|billy|wilma'
% logdefaults ... vector of length four containing four integers which are the 
% 		defaults for the four logs. These are taken to be row indicies into
%		lognames
% coefs ... vector of length four containing the defaults for a,b,c, and d
% exps ... vector of length five containing the defaults for k,m,n,o, and p
% newlogdes ... default descriptor for the new log. (Its "name" will
%	be automatically implied by the mnemonic form its type.)
