myuifile.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 [file,path]=myuifile(hmasterfig,filtspec,dtitle,type,varargin)

% [file,path]=myuifile(hmasterfig,filtspec,dtitle,type)
% [file,path]=myuifile(hmasterfig,filtspec,dtitle,type,defaultfile)
%
% Provides a sane interface to uigetfile and uiputfile in that the
% position of the dialog box is adjusted such that its upper left
% corner is aligned with the upper left corner of the master figure.
% 
% hmasterfig     handle of the master figure
% filtspec       string specifying the filter specification in the file
%		         dialog. Will be the first argument to uigetfile or uiputfile.
% dtitle         string specifying the dialog title
% type           must be either 'get' or 'put' and determines whether uigetfile
%		         or uiputfile is called
% defaultfile    [optional] if present, the default filename for the 
%                get/put diaglog.  May also contain a directory name.
%
% A cancel is indicated by a value of 0 for 'file'
