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