mat(varargin)

function varargout = mat(varargin)
% MAT M-file for mat.fig
%      MAT, by itself, creates a new MAT or raises the existing
%      singleton*.
%
%      H = MAT returns the handle to a new MAT or the handle to
%      the existing singleton*.
%
%      MAT('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in MAT.M with the given input arguments.
%
%      MAT('Property','Value',...) creates a new MAT or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before mat_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to mat_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
