% CONVDIFFGUI MATLAB code for convDiffGUI.fig
%      Group: Ashwin, Jerik, Remil, Sunil.
%
%      To open the GUI, run this file please. This requires all other
%      dependent functions: CONVECTIONDIFFUSION, CONVDIFFCD, CONVDIFFPU and
%      convDiffGUI.fig to be in the same folder.
%      CONVDIFFGUI, by itself, creates a new CONVDIFFGUI or raises the existing
%      singleton*.
%
%      H = CONVDIFFGUI returns the handle to a new CONVDIFFGUI or the handle to
%      the existing singleton*.
%
%      CONVDIFFGUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in CONVDIFFGUI.M with the given input arguments.
%
%      CONVDIFFGUI('Property','Value',...) creates a new CONVDIFFGUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before convDiffGUI_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to convDiffGUI_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
%      
%      CONVDIFFGUI was created as part of the submission for assignment
%      3. This is GUI for RODTEMPERATURE: the function that solution to the
%      diffusion equation using finite volume method on a uniformly heat 
%      rod of uniform conductivity and cross sectional area.
