function varargout = gskmadechar(varargin)

% GSKMADECHAR M-file for gskmadechar.fig

% GSKMADECHAR, by itself, creates a new GSKMADECHAR or raises the existing

% singleton*.

% H = GSKMADECHAR returns the handle to a new GSKMADECHAR or the handle to

% the existing singleton*.

% GSKMADECHAR('CALLBACK',h ,eventData,handles,...) calls the local

% function named CALLBACK in GSKMADECHAR.M with the given input arguments.

% GSKMADECHAR('Property','Value',...) creates a new GSKMADECHAR or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before gskmadechar_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to gskmadechar_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".
