%RUN_OFFSET_SIM M-file for run_offset_sim.fig
%      RUN_OFFSET_SIM, by itself, creates a new RUN_OFFSET_SIM or raises the existing
%      singleton*.
%
%      H = RUN_OFFSET_SIM returns the handle to a new RUN_OFFSET_SIM or the handle to
%      the existing singleton*.
%
%      RUN_OFFSET_SIM('Property','Value',...) creates a new RUN_OFFSET_SIM using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to run_offset_sim_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      RUN_OFFSET_SIM('CALLBACK') and RUN_OFFSET_SIM('CALLBACK',hObject,...) call the
%      local function named CALLBACK in RUN_OFFSET_SIM.M with the given input
%      arguments.
