function varargout = thermal_lens(varargin)

% THERMAL_LENS M-file for thermal_lens.fig

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

% singleton*.

%

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

% the existing singleton*.

%

% THERMAL_LENS('CALLBACK',hObject,eventData,handles,...) calls the local

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

%

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

% existing singleton*. Starting from the left, property value pairs are % applied to the GUI before thermal_lens_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to thermal_lens_OpeningFcn via varargin. %

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
