function varargout = segymat(varargin) % segymat : Garphical User Interface for SegyMAT % % (C) 2001-2004 Thomas Mejer Hansen, tmh@gfy.ku.dk/thomas@cultpenguin.com % % SEGYMAT M-file for segymat.fig % SEGYMAT, by itself, creates a new SEGYMAT or raises the existing % singleton*. % % H = SEGYMAT returns the handle to a new SEGYMAT or the handle to % the existing singleton*. % % SEGYMAT('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SEGYMAT.M with the given input arguments. % % SEGYMAT('Property','Value',...) creates a new SEGYMAT or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before segymat_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to segymat_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
