function varargout = radarsim(varargin)
%RADARSIM M-file for radarsim.fig
%      RADARSIM, by itself, creates a new RADARSIM or raises the existing
%      singleton*.
%
%      H = RADARSIM returns the handle to a new RADARSIM or the handle to
%      the existing singleton*.
%
%      RADARSIM('Property','Value',...) creates a new RADARSIM using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to radarsim_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      RADARSIM('CALLBACK') and RADARSIM('CALLBACK',hObject,...) call the
%      local function named CALLBACK in RADARSIM.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
