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