% comparezsc gui to compare multiple LISST backscatter calibration files
%
% reads backscatter data generated by LISST.EXE, which are simply an
% ASCII flat file of the 40 raw data values output by the LISST

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