| function varargout = interface_sofiene(varargin)
% INTERFACE_SOFIENE M-file for interface_sofiene.fig
% INTERFACE_SOFIENE, by itself, creates a new INTERFACE_SOFIENE or raises the existing
% singleton*.
%
% H = INTERFACE_SOFIENE returns the handle to a new INTERFACE_SOFIENE or the handle to
% the existing singleton*.
%
% INTERFACE_SOFIENE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in INTERFACE_SOFIENE.M with the given input arguments.
%
% INTERFACE_SOFIENE('Property','Value',...) creates a new INTERFACE_SOFIENE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before interface_sofiene_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to interface_sofiene_OpeningFcn via varargin.
